This one omitted quite a bit. A slight disappointment. 1. Tasić was actually in his third consecutive 12-hour shift as an ATC, which greatly contributed to his errors. 2. The last communication between Adria 550 and ATC was done not in English; due to stress Tasić reverted to Croatian, so even if the BA crew were listening, they had no idea what the two are saying. 3. The controllers at Zagreb were complaining for years about being understaffed and having primitive and faulty equipment, despite Zagreb being a very busy hub connecting the Middle East and Arabia with western Europe. 4. The radar Zagreb ATC was using was messed up and had a margin error of 500 feet. It showed the BA flight at FL335 (33500 ft), while the FDR clearly showed the Trident at FL330, as cleared earlier. This is why Tasić ordered Flight 550 to stay at exactly 33000 ft. Hope for a remastered and expanded version in the future.
Yes, exactly..the ATC did speak in Croation to Adria 550 & that's why the BA pilots didn't & couldn't react. I saw another breakdown of this incident just the other day.
No he didn't order them to level off at 330. They reported being at 325 and then he told them to level off as the British plane was at FL330. He tried to avoid the collision by telling them.tonstop climbing asap, and used Serbian probably to make it quicker...sadly...meanwhile the plane kept climbing. By the time they understood and had reacted they were at FL330. Just like that Indian mid air in 1996...a alas minute attempt to avoid the collision resulted in the collision actually happening. The language didn't make a difference, there wouldn't have been time to react, the British Pilots would have had to know not just the altitude but also the location
On Point 2. There’s speculation that the reason Tasic reverted to Croatian was to hide the airprox from the British crew. That way (had it become a near miss and not a collision), the Trident crew would have been none the wiser and not lodge a report. Wouldn’t have kept the Adria crew from reporting, but it would have kept it from being an international interaction. Hope that makes sense ?
New York Times, Sept. 11, 1976: “I heard a tremendous noise,” said Marica Boadjinec, a farmer who lives in the village of Vrbovc, about 15 miles northeast of Zagreb. “I looked up and saw a plane burning and coming apart, and the other plane falling on a cornfield about a kilometer from my courtyard.” Other witnesses said bodies and luggage rained down over an eight‐mile area, with the wreckage of the planes falling about a mile apart. A policeman, Garo Tomaevic, was one of the first to arrive at the scene. “I saw parts of the British plane, bodies lying all around,” he said. “There was a baby still giving feeble signs of life near the plane, but it was in last agony. Even if the ambulances had arrived before me, it would have been too late to save it.”
There was a lot more to this than reported including that Tasic had not had proper sleep because his house was located by a runway and as said he did not have an assistant. He was not supported during this busy shift but was put up as a scapegoat by the authorities. he did his best.
Yugoslavia was a communist dictatorship back then so human errors were likely deemed inexcusable. Glad someone there had the decency to realize Tasic was used as a scapegoat.
Another great video, Allec! One of the watershed accidents in aviation history, and a classic one in which a whole chain of events all had to happen in order for the accident to occur. There was plenty of blame to go around in this one, the ATC folks, the pilots of both aircraft . . . One of the accidents that helped to drive the development of the TCAS systems all airliners fly with today, to provide automated detection of potential collision and guidance to flight crews to prevent them from happening. The technology wasn't available back then, but it's all in place today, and it works.
I was a flight attendant in the UK and was in the air working on a flight to one of the Greek Islands on that day--it was only my third month flying--I was 21. We were in the vicinity of the collision and when we landed the flight crew informed us of what had happened. It was a very somber trip back and i don't think that our inbound passengers were aware of what had happened. RIP to all lost😢
Thanks for this report, Allec. You do quote from operations Handbooks of both, British Airways and Inex Adria where they state that it is the pilots responsibility to constantly observe the airspace. While this rule certainly has it's merits, it's worth to note that in the jet age other airplanes are very, very hard to see, especially when they are at the same flight level, also taking into account the high closure rate at these speeds. Add to this the mostly white liveries of the aircraft at this time and you will agree that seeing, let alone identifying another aircraft at these flight levels and at these speeds merely is a coincidence. As an ex ATP i've been there and done that.
Absolutely agree, see-and-avoid is not something that one does flying IFR in fast jets. Big point made of this at the time, mainly by non-aviation types at the trial.
In a collision between any two objects travelling in straight lines the closing angles change very little, if at all. This makes one object very difficult to acquire quickly when seen from the other. Also, in this case, some of the conversation between Zagreb ATCC and Adria 550 was conducted in Croatian/Yugoslavian which would have made it almost impossible for BE476's crew to appreciate and react to the impending peril
@@5milessep- Indeed; "see-and-avoid" is not really something one *can* do in cruise, due to the velocities involved. On top of that, given that the flight paths intersected at a near right-angle, neither flight crew stood a chance.
At least this is more appropriate than the Uberlingen accident because the lone controller was only jailed but later released. Unlike the latter, the controller was killed only because an angry father thinks Peter was responsible for the death of his family, but it was Skyguide's negligence that caused the accident.
Agree. The real scandal was Skyguide was never trialed or made accountable for the disaster. They left the controller completely alone with radar equipment under maintenance.
Thanks for making these videos. I been your fan for a while now and you seem very dedicated and knowledgeable in these matters and appreciate your hard work. Thanks.
Hey Allec, great video. You might want to correct the text at 2:41, the Trident was at FL330 and not FL300. A key point I’d like to make is the idea of the pilots keeping a watch out for other traffic is really not a causal factor whatsoever. The pilots were flying IFR, there’s no looking out for other aircraft. I know this was a big point made at the trial, but it was made by people with no aviation experience. The cause was a systemic failure of the ATC system at the time, and you cover much of that. Thanks for posting.
@@gusmc01 the Trident was at its planned cruising altitude of 33000ft, the investigators even pulled the radar tapes from Vienna ATC which showed it at exactly FL330.
Right, but as the Flight Levels are at even or odd thousands of feet, it's understandable. IF there's confusion as there was here. I recall flying from LA to SD southwards in a Piper Cherokee, we basically paralleled Interstate 5 Fwy. The set altitude for N to S was 1,000' vertical separation from S to N traffic. Man you could see the other planes coming probably 1 per minute, the other direction, very easily. I recall thinking, that's pretty close - what if somebody carelessly drifted up or down ? And that was GA planes at FL 100 going 120 knots. Just think how much faster trouble finds you at FL 300 & 350 knots ! RIP to all these poor Souls, in Jesus name !
The report that seemed to criticize the ‘scanning’ for nearby aircraft: it may have been a useful action for biplanes, but closure rates and airframe visibility of modern ships at the same altitude is very limited in usefulness.
Thankfully this happened over farmland and not the city of Zagreb itself otherwise the death toll could have been much higher. I think this was the disaster that forced big changes in ATC and aviation in general including use of TCAS
The CVR had not been working on the DC-9 but the collision jolted it into action. It recorded First Officer Ivanus’s last words as his stricken aircraft tumbled towards the ground: “we are finished. Goodbye” he said, “goodbye” The Trident First Officer seemed more preoccupied by grocery prices than monitoring the airspace around his aircraft. Total tragedy. RIP to everyone lost in this awful accident.
These accidents, where circumstances upon circumstances pile one on top of another and a miniscule change in any of them would have made this outcome different are always going to happen in commercial aviation. With hundreds of thousands of planes, millions of flight hours and densely packed air routes strung like a spider's web all over the world, it is statistically inevitable. Tenerife, JAL 123, United 191 and dozens of other major disasters all the result of an unimaginable combination of circumstances coming together at the exact moment...its unavoidable.
I would disagree. Air travel in the USA has been very safe for over a decade now due to in advances in technology and lessons learned from previous mistakes.
It is a good video, but many facts are missing. Like the real photos of the accident which has many. Or that poor Tasić died young soon after he was released from prison. Some true facts can be see in the comments. Also, a new documentary about this colission was made by the croatian television where they interviewed many witnesses. It is in croatian language, but some parts are in english like the interview of members of the family of one english passanger that visited the crashing site. The documentary is called "Padala su tijela".
This was a horrible reminder of too much for one air traffic controller to handle. This sad tragedy and despite it happened 47 years ago, still can haunt anyone to this day. The Inex Adria DC-9, designated as F550 was flying at it's assigned altitude and it's crew were waiting for confirmation to climb at a much higher level, however, they were given clearance to proceed for FL350 from their already "leveled-off" altitude of FL260, and when they were eventually transfered to Zagreb control, they were dealing with a busy airway that was then coupled to hit the presumably "stressed," controller, who was one Gradimir Tasic. The DC-9 crew, were waiting for over a minute to be handed over to Zagreb, while they must've already been flying over Zagreb airspace, and their airplane was exactly where it was supposed to be. The DC-9 was confirming it had passed 290 and climbing, but it's crew was told to maintain at 330. It was seemingly noticable that Mr. Tasic had a lot on his hands to deal with during this point. If Tasic had assistance along side of him, handling traffic in the vicinity around Yugoslavia, and other aircraft, most notably a British Airways Trident operating as F476, which was nearing the area, the tragedy would've never happened. The Trident was cruising at FL330, and the BA 476 crew were apparently not receiving the important calls from the tower about a potential "conflict". The BA airplane was traveling in a southeasterly heading, while the Adria airplane was traveling a northwest heading towards Germany. Tragically, this became a very sad result. Mr. Tasic did his very best to confront the situation at hand, but when the workload goes overboard for such an important task, he could've quickly gotten "side-tracked", and the unfortunate thing is that he was held to blame. It was only Tasic who seemed to be handling two separate sectors on the same airway. The unfortunate horror was that there were only a few seconds to spare, in which the collision could've been avoided. It instantly was not Tasic's fault as they later determined, because his fellow colleagues fought for him. He served a shorter prison sentence. Today, with better equipment, and controller awareness and resource management, should prevent anything like this from ever happening again. Rest in peace to all who tragically died in this tragedy.✝️🙏 Thank you for showing the video!!
7:25 the reason british pilot didn't react was the controller told 550 imminent danger in serbo croatian languange (refer to their natives tongue), british pilot didn't understand that
In Soviet block countries it was never the idea of analyzing the system, as the system can't be wrong. The accident was caused by the controller as he wasn't doing his job - at least this was the reasoning they used during the trial. Living in Communism/Socialism is much different than what normally one is used to.
@@matejfele9971 Yugoslavia, 1976. Are you sure about that? I am your neighbour, to the North, and we were also soviet block. You can call it soviet influence as well, but even if you disagree with that, we can agree, that the sentencing and how he was used a scape goat is very common for that era.
No blame should be attached to the flight crews. This tragic accident was caused entirely by inadequate ATC services. Flying on an IFR flight plan in VMC conditions, see and avoid does play a part in collision avoidance, however, numerous other flight deck duties and the airspeeds involved, it cannot be relied upon.
Just the morons who managed the ATC system. They should have been held accountable and I suspect were political cronies. Thank God the ATC system in the USA, while not perfect, is not like this.
The upper controller should have stated the altitude he wanted them to hold, not state their "current altitude". Far too ambiguous and this cost precious time as the pilots tried to clarify. The mid controller's request to squawk standby should have been investigated. Overall the ATC in that area needs a complete retraining
Ha! And people want flying cars. Sheesh! If a massive airspace such as in this video can result in a collision, then flying cars operated by humans is not a great idea. We can't keep our shit together on the relatively flat plain of a road, so the thought of a bunch of suburbanites flying into their garage/hangars at the end of the day, with Tarquin waving to Dolly, in a hope that she'll accidentally flash him an acknowledgment, after dropping from 5000 metres to sea level as he chugs a coldy after stopping on the way home at the sky-high bottle store, does fill me with some trepidation. Over thinking things? Probably.
Looks like "Corporate" was trying to cut corners & have just one person instead of 2.. The other is having Situational Awareness as we're not traveling on some Interstate..
My late father flew Tridents for BA and knew one of the First Officers lost in this accident, most likely FO Flint since he was the same age as my father at the time. It is entirely unfair to blame the BA crew for not reacting to the radio transmissions to the other aircraft that preceded the collision, since those transmissions were made in Serbo-Croat, which of course none of them spoke. Worth mentioning also is that Tasic’s display incorrectly showed the BA flight at FL335, which is why he instructed the Adria flight to level off at FL330, if they had continued climbing at the rate they were then the collision would most likely have been avoided. One minor detail, BA did not operate the Trident with a Flight Engineer, but with a third pilot manning the Technical Panel.
You missed a critical detail. The warning radioed by Granimir Tasic to the yugoslav aircraft was in serbo-croat language. This way the BA crew even if they heard it they could not understand it and get alerted of traffic conflict. Also first officer of BA aircraft was not looking out for traffic, from the CVR recording it appeared he was busy with a crossword puzzle.
Scanning for traffic at 800 kts? Really? You expect pilots to see an airplane coming, at that speed, in any direction, and react in time to avoid a collision? Impossible. But sure, pilots always to blame... This one is all controllers fault. They didn't coordinate between themselves and sent a plane right to the path of the other. 99% middle sector's fault. Simple: Do not send a plane to a FL you don't control and you are not aware of its traffic. You send them there blind.
Brilliant Video as usual, but sadly the Trident is in the wrong livery. It was the BEA 'Speedjack' colours, but had British Airways on as opposed to BEA.
They died istantly, they didn't realize it. Instead the crew of Inex aircraft was well aware during the fall to the ground. CVR recorded the desperate words of first officer while the aircraft was diving uncontrolled to the ground...: "...joi, joi,...gotovi smi, gotovi smi....vatra !" (...god, god...we're finished, we're finished...fire !"
both aircraft were in controlled airspace, but the controllers did not have situational awareness due to the lack of manpower and equipment. The BA crew would not have been able to see the DC 9 against the background as it was in a level that obscured it; the Adria crew would not have seen the Trident as they were looking for traffic above them but having overshot the FL that the controller thought they were at weren't advised correctly, so they were given wrong information. This crash was a product of the p*ss poor ATC at Zagreb, both sets of pilots were let down badly by the Zagreb controllers and the Yugoslavian government.
CORRECTION: The ATC System dropped the ball, not the poor ATC on duty. (36) hours on duty straight. The morons who managed the ATC System are the ones who should have been jailed. Everyone is forgetting the burden that the ATC carried with him for the accident for the rest of his life.
can make korean air flight 858 with the crash animation from the movie but in the movie the plane is a airbus a300 but in real life the plane is a boeing 707.
La collision est le résultat d'une erreur de procédure de la part des contrôleurs aériens de Zagreb.Honteux il à fait que deux ans de prison ,,,,,,,, honteux, honteux, honteux
Yes but if same ATC conttoller had been directing same planes they eojlfnt have bern within 50 feet of each othervif domeone had checked heading hiven go them snd it had befn same controller as other plane doneone woupd have spotted it and quickly got over plsne to divert yes they dhould hsvs scanned but isnt TCAS for that purpose they were at gailt pilots but not 100% fault
Wasn’t TCAS available by this date? How do you expect flights to be safe when pilots have to look out for crossing traffic? What about the 1000ft separation rule? What would be expected of crews in bad visibility? Upper level controller was certainly a scapegoat for an appalling setup on the ground.
TCAS wasn't standardized until the early 1980's. There were transponder systems available before then but they were used for ground control (ATC), not the flight deck. It wasn't until the mid-1970's that research was started on how to get transponders signals to act as an avoidance system within the flight deck itself.
@@gsdalpha1358 Thank you for that info; we were crossing the centre of Paris in a summer holiday flight from Greece to Bristol, about ten years ago. I was looking out and saw a twin jet pass under us no more than fifty foot underneath us. I could see both pilots staring up looking astonished. Could have been curtains for a good bit of Paris. It was never reported but seemed like an ATC error. You get more than you expect on a TUI holiday. 😳
@@martinross5521i had a somewhat similar experience about 5 years ago when flying around Argentina i saw a plane coming from opposite direction about 150 mts on our right, same flight level. I was sitting next to the window and i was just shocked. Not a single hint of what happened from the pilots when we arrived and i tried to search later for some reports but no luck.
As usual it was the ‘Soviet’ side that caused the crash, this time with their ridiculous ATC working pattern. No wonder Aeroflot has the worst safety record. They can barely drive cars
C'est en ignroant les erreurs du passé qu'on se condamne a faire les mêmes conneries This is as ignorant of the past errors we will condemn to make the same idiocies.
Didnt the accident happen at night? why does this show as if it happend during the day edit it did happen on daylight... weird since most mid air collisions happend at night
The sub-titles are so rushed (especially towards the story building part) that it ruins the continuity of the video. TFC does a much better job of timing the sub-titles consistently. No thumbs up, or "like" today because of this. Are you still angry folks prefer the sub-titles over the narration? Would still rather have sub-titles rather than narration, although it spoils the video when I have to "pause" the video so many times.
TFC also uses CLICKBAIT thumbnails wh. exaggerate the seriousness of the video. Yesterday's TFC video completely neglected to follow up on what happened when the aircraft was lost on take off. Ibay's videos contain non of this; they're well thought out and provide us with facts, not SENSATIONALISM.

The DC-9 was confirming it had passed 290 and climbing, but it's crew was told to maintain at 330. It was seemingly noticable that Mr. Tasic had a lot on his hands to deal with during this point. If Tasic had assistance along side of him, handling traffic in the vicinity around Yugoslavia, and other aircraft, most notably a British Airways Trident operating as F476, which was nearing the area, the tragedy would've never happened. The Trident was cruising at FL330, and the BA 476 crew were apparently not receiving the important calls from the tower about a potential "conflict". The BA airplane was traveling in a southeasterly heading, while the Adria airplane was traveling a northwest heading towards Germany. Tragically, this became a very sad result. Mr. Tasic did his very best to confront the situation at hand, but when the workload goes overboard for such an important task, he could've quickly gotten "side-tracked", and the unfortunate thing is that he was held to blame. It was only Tasic who seemed to be handling two separate sectors on the same airway. The unfortunate horror was that there were only a few seconds to spare, in which the collision could've been avoided. It instantly was not Tasic's fault as they later determined, because his fellow colleagues fought for him. He served a shorter prison sentence. Today, with better equipment, and controller awareness and resource management, should prevent anything like this from ever happening again. Rest in peace to all who tragically died in this tragedy.✝️🙏
Thank you for showing the video!!
7:25 the reason british pilot didn't react was the controller told 550 imminent danger in serbo croatian languange (refer to their natives tongue), british pilot didn't understand that
Who would take a job that could result in a long prison sentence for making a mistake? Only a perfectionist who was actually capable of perfection.
In Soviet block countries it was never the idea of analyzing the system, as the system can't be wrong. The accident was caused by the controller as he wasn't doing his job - at least this was the reasoning they used during the trial. Living in Communism/Socialism is much different than what normally one is used to.
@@n0rbert79 That country was never a part of the soviet block. The rest I agree with.
@@matejfele9971 Yugoslavia, 1976. Are you sure about that? I am your neighbour, to the North, and we were also soviet block. You can call it soviet influence as well, but even if you disagree with that, we can agree, that the sentencing and how he was used a scape goat is very common for that era.
@@n0rbert79 Yes I'm sure :)
Police live with that situation daily.
Wow, that was quick & unexpected in this video.
*shows mid air collision
*ad pops up: *try our new Kingsland Pasta at Outback Steakhous-*
The odds, at that speed and altitude of reaching that exact point at that exact time? Unbelievable(ly) sad.
No blame should be attached to the flight crews. This tragic accident was caused entirely by inadequate ATC services. Flying on an IFR flight plan in VMC conditions, see and avoid does play a part in collision avoidance, however, numerous other flight deck duties and the airspeeds involved, it cannot be relied upon.
Goldenwest Flight 261, I don't think Allec has ever done this one.
crazy to think this has happened in my city when i wasn't born yet......
Weird comment..
It seems to me that everyone involved was guilty of mistakes that made this disaster happen.
Yes it's as they've said for a long time it's almost never just one cause.
Not pilots fault.
Just the morons who managed the ATC system. They should have been held accountable and I suspect were political cronies. Thank God the ATC system in the USA, while not perfect, is not like this.
The upper controller should have stated the altitude he wanted them to hold, not state their "current altitude". Far too ambiguous and this cost precious time as the pilots tried to clarify. The mid controller's request to squawk standby should have been investigated. Overall the ATC in that area needs a complete retraining
How do you find the photos of the actual airlines involved in the crashes you post ?? I've always been curious about that
Horrific!
Jesus that thumbnail look absolutely brutal
Ha! And people want flying cars. Sheesh! If a massive airspace such as in this video can result in a collision, then flying cars operated by humans is not a great idea. We can't keep our shit together on the relatively flat plain of a road, so the thought of a bunch of suburbanites flying into their garage/hangars at the end of the day, with Tarquin waving to Dolly, in a hope that she'll accidentally flash him an acknowledgment, after dropping from 5000 metres to sea level as he chugs a coldy after stopping on the way home at the sky-high bottle store, does fill me with some trepidation.
Over thinking things? Probably.
Looks like "Corporate" was trying to cut corners & have just one person instead of 2.. The other is having Situational Awareness as we're not traveling on some Interstate..
How accurate are altimeters? 309 foot separation seems cutting it very close.
How the crazy 2 people survived this collision
@@donnabaardsen5372not really a spoiler Donna as they both ended up succumbing to their injuries.
@SteviPantyhose-mt5lm Are you liking all your own comments?
There are often spoilers on this channel. Watch in “Full Screen” to avoid these spoilers.

@SteviPantyhose-mt5lm oh my!
My late father flew Tridents for BA and knew one of the First Officers lost in this accident, most likely FO Flint since he was the same age as my father at the time.
It is entirely unfair to blame the BA crew for not reacting to the radio transmissions to the other aircraft that preceded the collision, since those transmissions were made in Serbo-Croat, which of course none of them spoke.
Worth mentioning also is that Tasic’s display incorrectly showed the BA flight at FL335, which is why he instructed the Adria flight to level off at FL330, if they had continued climbing at the rate they were then the collision would most likely have been avoided.
One minor detail, BA did not operate the Trident with a Flight Engineer, but with a third pilot manning the Technical Panel.
In the USA, ATC controllers are required to retire at 56.
...and?
Do you consider his decrepitude contributed to the accident?
Do you think it was a factor?
What are the odds of this happening? Tragic
You missed a critical detail. The warning radioed by Granimir Tasic to the yugoslav aircraft was in serbo-croat language. This way the BA crew even if they heard it they could not understand it and get alerted of traffic conflict.
Also first officer of BA aircraft was not looking out for traffic, from the CVR recording it appeared he was busy with a crossword puzzle.
Scanning for traffic at 800 kts? Really? You expect pilots to see an airplane coming, at that speed, in any direction, and react in time to avoid a collision? Impossible. But sure, pilots always to blame... This one is all controllers fault. They didn't coordinate between themselves and sent a plane right to the path of the other. 99% middle sector's fault.
Simple: Do not send a plane to a FL you don't control and you are not aware of its traffic. You send them there blind.
Brilliant Video as usual, but sadly the Trident is in the wrong livery. It was the BEA 'Speedjack' colours, but had British Airways on as opposed to BEA.
i went to zagreb earlier this month omg
Yugoslavia's Worst Air Disaster | Zagreb Mid-Air Collision
Yugoslavia's Worst Air Disaster | Zagreb Mid-Air Collision
🤔🤐🤨 , A lack of clear comunication in the control tower was the reason for this tragedy .
"Sliced through the cockpit" I feel bad for those pilots. Jesus.
They died istantly, they didn't realize it. Instead the crew of Inex aircraft was well aware during the fall to the ground. CVR recorded the desperate words of first officer while the aircraft was diving uncontrolled to the ground...: "...joi, joi,...gotovi smi, gotovi smi....vatra !" (...god, god...we're finished, we're finished...fire !"
Damn
The text is difficult to read. A more solid, darker version is needed.
both aircraft were in controlled airspace, but the controllers did not have situational awareness due to the lack of manpower and equipment. The BA crew would not have been able to see the DC 9 against the background as it was in a level that obscured it; the Adria crew would not have seen the Trident as they were looking for traffic above them but having overshot the FL that the controller thought they were at weren't advised correctly, so they were given wrong information. This crash was a product of the p*ss poor ATC at Zagreb, both sets of pilots were let down badly by the Zagreb controllers and the Yugoslavian government.
1976 Zagreb mid-air-collision British airways and inex-Adria airways aircraft
Good but personally the sad music just gets to me, especially as it crescendos louder. Unnecessary. Thanks
The ATC really dropped the ball on that one. Horrible loss of life, I remember the report on the evening news, I was really shocked.
CORRECTION: The ATC System dropped the ball, not the poor ATC on duty. (36) hours on duty straight. The morons who managed the ATC System are the ones who should have been jailed. Everyone is forgetting the burden that the ATC carried with him for the accident for the rest of his life.
As a pilot believe your instruments
So the pinned the blame on one guy and made no procedural changes.
SOP
I thought it was a JAT airplane that had issues with their radio
British Airways is still the only MAJOR airline to have never lost a passenger in the air due to airline negligence. The best of the best.
The Staines crash in ‘72 ?
What about Qantas?
Qantas?
Yes, Qantas has never lost a passenger!@@0w3nn
Remake of United Airlines Flight 175, please
How were there two survivors from a plane crash at 30000 feet?
5:27
can make korean air flight 858 with the crash animation from the movie but in the movie the plane is a airbus a300 but in real life the plane is a boeing 707.
La collision est le résultat d'une erreur de procédure de la part des contrôleurs aériens de Zagreb.Honteux il à fait que deux ans de prison ,,,,,,,, honteux, honteux, honteux
Chad still using FS 2004 in 2023
No excuse.
It was the ATC’s fault who spoke his native Serbo-Croatian language contacting the second airline.
Over Simplification.
Sickening and scary
Inex-Adria Aviopromet's Flight 1308 was the worst.
Tragic
Were either of the aircraft repaired and returned to service?
They were both destroyed beyond repair and were in pieces
You must be kidding.
@@deepthinker999 nope
interesting
It baffles me why airplanes have no side/rear view mirrors and signal/break lights.

Yes but if same ATC conttoller had been directing same planes they eojlfnt have bern within 50 feet of each othervif domeone had checked heading hiven go them snd it had befn same controller as other plane doneone woupd have spotted it and quickly got over plsne to divert yes they dhould hsvs scanned but isnt TCAS for that purpose they were at gailt pilots but not 100% fault
Wasn’t TCAS available by this date? How do you expect flights to be safe when pilots have to look out for crossing traffic? What about the 1000ft separation rule? What would be expected of crews in bad visibility? Upper level controller was certainly a scapegoat for an appalling setup on the ground.
TCAS wasn't standardized until the early 1980's. There were transponder systems available before then but they were used for ground control (ATC), not the flight deck. It wasn't until the mid-1970's that research was started on how to get transponders signals to act as an avoidance system within the flight deck itself.
TCAS was decades away
@@gsdalpha1358 Thank you for that info; we were crossing the centre of Paris in a summer holiday flight from Greece to Bristol, about ten years ago. I was looking out and saw a twin jet pass under us no more than fifty foot underneath us. I could see both pilots staring up looking astonished. Could have been curtains for a good bit of Paris. It was never reported but seemed like an ATC error. You get more than you expect on a TUI holiday. 😳
@@martinross5521 Yikes!!!
@@martinross5521i had a somewhat similar experience about 5 years ago when flying around Argentina i saw a plane coming from opposite direction about 150 mts on our right, same flight level. I was sitting next to the window and i was just shocked. Not a single hint of what happened from the pilots when we arrived and i tried to search later for some reports but no luck.
😢😢😢😢
As usual it was the ‘Soviet’ side that caused the crash, this time with their ridiculous ATC working pattern. No wonder Aeroflot has the worst safety record. They can barely drive cars
There is no soviet here anywhere.
5:57 *OMG* 😱
you keep chewing this almost forty-year-old stuff, missing the point all the time
C'est en ignroant les erreurs du passé qu'on se condamne a faire les mêmes conneries
This is as ignorant of the past errors we will condemn to make the same idiocies.
Trump was supposed to be on one of the planes but cancelled at the last minute. I vaguely recollect a news article from that time.
Didnt the accident happen at night? why does this show as if it happend during the day
edit it did happen on daylight... weird since most mid air collisions happend at night
It happened on broad daylight, around 10 AM.
Technology is great...but sometimes you have to look out the window.
At another plane approaching at 500mph. Yeah, you're gonna move out the way aren't you?
The sub-titles are so rushed (especially towards the story building part) that it ruins the continuity of the video. TFC does a much better job of timing the sub-titles consistently. No thumbs up, or "like" today because of this. Are you still angry folks prefer the sub-titles over the narration? Would still rather have sub-titles rather than narration, although it spoils the video when I have to "pause" the video so many times.
TFC also uses CLICKBAIT thumbnails wh. exaggerate the seriousness of the video. Yesterday's TFC video completely neglected to follow up on what happened when the aircraft was lost on take off. Ibay's videos contain non of this; they're well thought out and provide us with facts, not SENSATIONALISM.
@@johannesdenholt4928 EXACTLY !!!
Very poorly reaearched video. VERY DISAPPOINTED
Damn! I knew what he meant as soon as he said it, stop your climb and maintain current flight level. Not proceed up to 33!!! Damn it, confusion!
