- British European Airways Flight 548 was a scheduled passenger flight from London Heathrow to Brussels that crashed near the town of Staines, England, soon after take-off on 18 June 1972, killing all 118 people on board. The accident became known as the Staines air disaster. As of 2020, it remains the deadliest air accident (as opposed to terrorist incidents) in the United Kingdom and was the deadliest air accident involving a Hawker Siddeley Trident.
The aircraft suffered a deep stall in the third minute of its flight and crashed to the ground, narrowly missing a busy main road. The inquest principally blamed the captain for failing to maintain airspeed and configure the high-lift devices correctly. It also cited the captain's heart condition and the limited experience of the co-pilot, while noting an unspecified "technical problem" that the crew apparently resolved before take-off.
The crash took place against the background of a pilots' strike that had caused bad feelings between crew members. The strike had also disrupted services, causing Flight 548 to be loaded with the maximum weight allowable. Recommendations from the inquiry led to the mandatory installation of cockpit voice recorders in British-registered airliners. Another recommendation was for greater caution before allowing off-duty crew members to occupy flight deck seats. Some observers felt that the inquiry was unduly biased in favour of the aircraft's manufacturers.

Due to the lack of voice recording no one knows who retracted the droops. All three crew were qualified on the Trident including captain Collins who was in the jump seat hitching a ride. Whatever happened on that flightdeck will forever remain a mystery. May they all rest in peace.
You showed the deep stall as a nose down descent. A deep stall is when the wings stall in a pitched-up attitude and place the elevator in a wide stream of turbulent air so that pitch control is lost. How it can be so easy for a passenger airliner to get into that irrecoverable corner of the envelope because even the captain sets the slats wrong is mind-boggling.
Great video! Where did you get the trudent from?
According to the data this Trident took off from 27R not 27L, both have now changed since 1987 to 28R & 28L. So behind the Trident as it starts it's take off should be the rental car bases & hotels etc .
Noise abatement procedures are absolutely dangerous(and really stupid) on after take-off climb.
It was a fact that should be pointed in the investigation..!
But there's so much idiots moving(rent or buy) to live close of busy airports and then cries like babies
about the noise... Unfortunately, it still the same almost 50 years later.
Most Likely That 2 People Both Passengers , survived initially but died from their injuries
This video is fairly well done, but the version of events it presents is largely speculative. (In terms of the flight-deck conversation presented, it is pure guesswork. There was no cockpit voice recorder on this aircraft). The flight-data recorder tells us exactly what happened, and when: but the why, the how and for that matter, the who - as pertains to certain actions or inactions (e.g. raising of the droop, cancellation of the stall warnings) - are destined to remain forever a mystery.
Just what I was going to to say. CVR became mandatory after this.
There was no cockpit voice recorder so all the dialogue in this video is pure conjecture. (one of the recommendations of the accident report was to require CVR on all british registered airliners).
I've always wanted to see this crash, thanks for making this.
@Matthew is The best Yes definitely.
@Matthew Leung internet has a lot of weirdos
One needs to speed read the graphics at the end. Whole video needs checking and quite a few improvements to be made. Thanks though.
You have no idea what was said in the cockpit
Uauhhhh. Thank you for this video. So sad, but did happen
Zacman your graphics roll like a Commodore 64. Love it
Was it possible there was a faulty lever causing the droops being retracted too early leading to a stall?
No it was cause by pilot error that retracts the droops too early
@@UNIQUEwastaken Yes true. However there is one, very important point here that’s being missed. There was, unfortunately a bad cockpit or ergonomic design. The Droop Lever was right next to the Flap Lever. They were separate devices, not combined, but with levers that were almost exactly the same right next to each other! They think that Capt Key was suddenly stricken with severe chest pain, probably he was suffering a major heart attack. He retracted the droops instead of selecting the next stage of flap, going towards up. Capt Key collapsed and was now probably dead, the young F/O didn’t monitor his Airspeed as was distracted by the dying Captain. The aircraft stalled then stick push was automatically applied two or three times! The F/O kept pulling the control column back, rather than pushing forward to regain his lost speed. He frantically kept pulling the nose up, aggravating the stalled condition. He lost patience and so cancelled the stick pusher manually. It was A Fatal Mistake! The Trident was now some thirty knots below minimum speed and with one final pull, he caused a large nose pitch up, the Trident now entered a Deep Stall, a condition from which recovery was now impossible, due to the stalled airflow travelling over the high T-Tail design, rendering the Elevators ineffective! The stricken Trident fell almost vertically into a field just on the other side of the A40 dual carriageway. All except One Passenger were killed instantly on impact! The passenger who survived the crash received fatal injuries and sadly died on his way to the Hospital. The First Officer Never Once Increased the Power to Full Power! Had he done so, and slightly lowered the nose by 10 degrees, Increased his airspeed by just 10kts, the Trident would have recovered from the stall and Powered out of the decent into a gradual climb back to 3000 feet and levelled off. Declared a Mayday. He could have then asked the third Pilot to set the power, operate the radios while he flew Radar Vectors into a rapid circuit, lowered the gear, deployed the flap and droop on speed schedule, carried out an Emergency Approach and Landing, back onto LHR Runway 28L, as it was then, it became 27L/ 27R. That’s all he had to do! He panicked, lost control of the Aeroplane and crashed! That’s what actually happened, as far as the investigation could tell! I’ve just added a bit of poetic license, to show what Jeremy Ticehurst should have done. Personally, I think he wasn’t ready to be on jets yet! He was too inexperienced to be flying the Trident. He needed another two or three years on the Turboprop Fleet first, probably the Vickers Viscount or the Vickers Vanguard. I had three and a half years on heavy turboprops before I transferred to the Boeing 737. Then a further five years before going onto the B747-400! Retired VAA Pilot.
Poor video explanation of this disaster. It states who said and did what, when in reality there was no CVR to record any of it. No real mention of the captains health issues that “may” also have played a big part in this. Shows the deep stall incorrectly and also the impact as a large breakup and explosion which also didn’t happen.
Sad
Is it even possible to have 29 hrs of flying (unless a student)?
Keighley was 22 and had joined line flying a month and a half earlier, with 29 hours as P2. His inexperience was one of many factors that caused the crash.
@@ZacmanAirDisasters Not sure if you are a pilot or not so please take what i say with the respect it is intended and my non-expert status. I have done flight school and it normally takes around 50hrs to obtain a Private Pilots License. Think propeller/4 seater airplane. In order to do that basic student license and then the follow up with the commercial license that you would need before you even touched a commercial plane , plus instruments rating and jet conversion it would suggest that at least a couple of hundred hours of flying experience. Clearly all of these guys had that but I think what you are referring to is the specific "line training" specific to the type of plane they were flying. The trident jet. This was limit to the number you mentioned. I tried to find more info for you...try seeing this article. The second pilots were indeed inexperienced but to suggest they only had 29 hours in total as commercial jet pilots may be a bit unfair and misleading. smhusain1.com/2016/06/11/the-trident-tragedy-1972/
Key had a heart attack , the junior pilots panicked and lost control ?
Possible. Everything, though, is speculation. We will never know what happened on that flight for sure.
@@SMSJSC It didn't explode on crashing as shown in the video thats for sure, it just broke up.
@@alangreen1650 Yes, the animation exaggerated that
Btw the F/O pulled the drools up accidentally
Nope, it was Captain Key.... Hope this helps : "As the plane climbed through 1,770 feet at a speed of 162 knots (300km/h), Captain Key inexplicably pulled the lever to retract the droops. He did so at the worst possible time. Because the droops add lift, they decrease the speed at which the plane will stall, enabling flight at lower speeds. Retracting the droops increased the Trident’s stall speed by about 30 knots, which happened to put it above the actual speed of the plane. Flight 548 instantly entered a stalled state with no advance warning whatsoever. Within three seconds of the retraction of the droops, a cascade of alarms and warning lights suddenly filled the cockpit. The autopilot disconnected and the “stick shaker” alarm activated, physically shaking the pilots’ control columns to alert them to the stall. At the same time, a safety system called the stick pusher sprang into action, moving their control columns automatically toward nose down in order to increase the plane’s speed and escape the stall situation. The rapid-onset emergency took Key, Keighley, and Ticehurst completely by surprise."
Sir the captain didnt retract the droop it was the first officer
15000 hours of flying-time and not able to fly as good as a beginner....
