- One person has been confirmed dead and multiple others injured, after a Singapore Airlines plane made an emergency landing in Bangkok's Suvarnabhumi Airport. Flight SQ321 was flying from London's Heathrow Airport to Singapore when it encountered severe turbulence and was diverted to the Thai capital. The Boeing plane was carrying 211 passengers and 18 crew. Thai authorities are set to hold a presser to address the incident. Mr Alvin Lie, an independent aviation analyst, shared more about different turbulence scenarios.

We should also thank Thailand for their help. 🙏
It’s a blessing that SIA pilot is able to land safely despite suffering such severe turbulence… thank you for your professionalism

Clear air turbulence! Now that’s something for you to know. It’s more dangerous than experiencing actual air turbulence because you have no prior knowledge of it coming and are ill-prepared for it. When the pilot says to fasten your seatbelts, take it seriously and DO IT! I reckon it’s best to be fastened to your seat 💺 all the time until it’s really necessary to go to the toilet! And make sure to make it quick at the restroom and get back to your seat and get fastened! 😅
You are the one and only who have sense in this case. Pilot with 26.000 hrs
It’s not CAT! Check the weather radar , it will tell you
Always keep your seatbelt on the whole flight as long as you are seated...
No!
Indeed
100%
Agree😊
Singapore Airlines is known as the best airline but things can always happen with the fluctuations in the weather. The captain was very good at deciding to make an emergency landing in Thailand.. Seeing the good help of Thailand, I feel admired and everyone. Very country should do the same help when emergencies like this occur.
Seat belts are so important, especially for long haul flights, too many don't bother with these safety precautions.
this news presenter is totally unprofessional... the invitee is extremely clear and coherent whilst she appears like a dumb journalist.
Keeps interjecting as if he's a hostile witness! Rude!
I was thinking the same, she has no IQ whatsoever!
i think shes missing what he’s saying as “clear” air turbulence, like airpockets
. it’s different than normal turbuluence caused by clouds which is visible in radar. this one wasnt visible at all so there was no warning.
I agree. She missed the point totally that clear air turbulence or air pocket are unpredictable and unavoidable for air travels..
@@snoopybrown2438 yeah the newscaster just seemed confused lol
Totally understandable. Average people will not know how "clear" air turbulence differ from normal turbulence or what does it mean by "clear" air. I dont even know there are different types of turbulence. I believe this is live and the newscaster wont be able to google what is "clear" air turbulence while in the interview.
Newscaster talk very very well, have lack listening skills
@@mysticv7177 Yah, you must be an aviation expert.
Kudos to the quick response of SIA pilots to make an emergency diversion to land at Bangkok intl airport…👏👏👏
Our condolences to the passing of the victim killed in this tradegy.
These Pilots did an absolutely amazing job! And well to the Thai Authorities, who was clearly very awesome in dealing with this emergency. They clearly have great emergency procedures and discipline, as they were ready and able to deal with this once the plane landed. Condolences to the family of the departed passenger. RIP.
Condolences to the family of the passenger who died and prayers for those injured towards a speedy recovery.
There you have it! Conclusion is drawn then. Clear air turbulence, excellent pilots, reliable plane, people didn't buckle up...
As a pilot, I'd say that's an excellent explanation! No fussing around.
are you a Singapore pilot???
Are you gay and rich or just military brat
I totally agree. I thought he gave an excellent analysis. Two key points he made supporting CAT is that pilots will avoid obvious CN clouds, especially near the tropical convergence zone, and secondly other planes would have been in the area, and no one was issuing warnings.
You sure ? Very sure ?
Sure bo pilot??
My uncle, who flew for SQ as a captain before he retired, says that turbulence is a fact of life when flying, It's no different than a boat at sea. One of his funnier stories was he was called to come see a passenger who asked him to make the plane stop shaking.
I flew to KL and onto HCMC & Jakarta for over 10 yrs. Very often experienced turbulance over the bay of bengal. One time in a thunder storm the plane actually got hit by lightening and diverted.
@@michaelhollingworth8905 "One time in a thunder storm the plane actually got hit by lightening and diverted."
Most of the time, lightning strikes on airplanes don't matter as the plane is made with that in mind, the current will just travel on the plane's skin and goes "out the back".
They may have diverted due to large amount or size of the thunderstorm at or near the destination and thus, unable to land there even if they perform holding pattern to wait it out. Better to land somewhere safe than risk running low/out of fuel at destination.
🙏😞❤️🇹🇭🙏🇸🇬Thank you Thailand for helping in this event! 🙏😞❤️🇹🇭🙏🇸🇬
Pilots did an amazing job, declaring emergency and immediately diverting to Bangkok. Condolences to the family of the deceased.
Pilots good, Boeing not!
@@alter1237 Please do not blame Boeing. If you come into so called CAT - clear air turbulence - it doesent matter what aircraft you have
@@blueseamarineltdblueseamar6053 Proof it
Why cant the pilot divert from the turbulence ?
@@bobafett5757because technology we have now cannot detect it
My worst experience of turbulence was a sudden drop of about 2-3 seconds flying thru bad weather from Jakarta to Singapore. And the drops happen many times along the trip. Not too scary for myself having done airborne jumps but very frightening for average individuals and children on the flight. And that was when we are EXPECTING turbulence as the pilots had warned us we’re flying thru bad weather. But turbulence causing the aircraft to drop from average 30,000 ft to 6,000 ft is almost like doing skydiving, worst is not expecting it while flying in CLEAR WEATHER! Only difference is the pilots managed to keep the aircraft IN CONTROL and land safely. That in itself…my utmost respect to the pilots!!
Condolences to the passing victim. It's heartbreaking to hear this.
Senior Flight Commanders are saying this turbulence is a normal event. The descent was normal. What is at issue is the initial 'bump' and passengers not being secured.
Thank you Thailand ❤
I once experienced turbulence with thunderstorm and heavy rains in the middle of the night when on my way to NY, the plane shakes rigorously a few times, I was so scared at that time and feeling very helpless. I closed my eyes and prayed and thought I shall accept what it come as I couldn’t escape anyway, putting my life to fate… fortunately , the turbulence stopped after a few minutes … that was my 23hrs flight in the air !
i once flew with Malaysia Airline, around 2003, flight from Stockholm - NYC… half way thru, when everyone was sleeping (night flight), trhe plane was shaking, roller coaster rides (dropping 1-2000ft each time) for almost an hour..i was about to sleep, and in my mind was that we’re gonna crash at some point… i quickly set my seat from bed to sitting position and tightens my seatbelt… that was the scariest flight i ever flown in my life….😰😨… i cant imagined SIA dropped 6000ft into an air pocket…that is scary !!!!!
How scary! How long after that did you feel safe enough to fly again?
That stat is misleading....5 minutes is a long time in flight time and 6000ft isn't that much. Think about it. A plane rising to 20.0000 feet after take off within 2-3 minutes. That is normal descent speed.
@ebhole why not you explain to the media and see the response 😮
Now clearly understood why good airlines like SQ are very strict on seat belts and also not serving hot bev when seatbelt signs are on
When flying over Bay of Bengal …. I always Seat belt on all the way ….. turbulence in that area famous .
Ditto, Bay of Bengal is the worst!
Bay of Bengal is worst in turbulence mainly from May to August monsoon seasons
Recall my friend said. (Many years ago)
The plane shaken violently. And a lot of Indian passengers prayed loudly.
Don’t think newscaster understands aviation expert !
That's why he's the expert and she's only a newscaster
His english is fine. Hes speaking slowly has an accent. 90% understandable. If he was speaking fast then maybe it would be hard
CNA Newscasters doing an Excellent Job in Damage Control to Rule Out Pilot Error, Equipment Malfunction , Poor Ground Support etc … No mention of Data from Black Box …Essentially, the Outcome rdy Predetermined … Accident owing to Severe Turbulence … Losses Covered by Insurance….
@@DaveSeville-sf1kuHe is Indonesian
according to uk passenger on board this flight, seat belt warning was announced before. and immediatey drop 6000 ft
No no. That can't be. They are talking about "clear" air turbulence.
@Traipai are you there ??
"Clearly" not. But if I am, I would love to talk to the media and share my harrowing experience.
Thank you thai friends for your assistance 🙏
Singapore airlines did very well, In Handle of this condition❤.
Then how come 30 passengers got injured can you justify ?
@@bobafett5757 If you can't predict the turbulence, you can't stop people from walking around in the plane. London to Singapore flight time is 13h 15m, why not you try sitting in your seat for the whole duration without going to the toilet or stretching your legs in economy class?
Silly you.???@@bobafett5757
WHY did she cut him off as he was speaking and then asked a question about something he had already mentioned at the start of the interview???
Thailand , by Suvarnabhumi airport run this situation as good as and OK! safety first.
Newscaster can’t understand what’s been said.
She's annoying.
@@margaretchong1450 she needs training
yea totally. she.s chewing so badly on her words. should be removed.

Hard to understand his accent. He’s baby taking too.
I was supposed to be onboard on this flight SQ321 back to Singapore but rescheduled to 22nd (same flight SQ321 ) instead because I’ve met an old friend and decided to extend for another day so that we could meet up for dinner, otherwise I could be one of the injured person. My condolences to the family of the deceased and at this difficult moment my thoughts are with them wholeheartedly & wishes those onboard who are injured a speedy recovery.
Impressive response by Thai Authority at the Airport. Well resourced first responders... done with urgency. Singapore Airlines, well done too.
I appreciate the explanation, thank you sir❣️
Very gd explanations Sir. Tq
Many took for granted when there is turbulence when it should not be taken lightly!
This sea region where it happened is like a Bermuda Triangle…turbulences regularly happens when flying through that area
this lady is being rather rude in her realm of questioning -
I think so.
It's American style reporting, arrogance with zero knowledge.
There is one passenger posted that the seat belt sign was not on. Whose responsibility to turn on the seat belt sign during such turbulence times?
Also shows how robust modern aircraft are!
So sad, my Mum takes this exact flight when she comes to KL to visit, that poor man was probably doing the same, heading to visit family with his wife, I can't imagine what she must be going through and the family. My thoughts are with them all and everyone affected, the skies are getting rougher, I've done been over this airspace quite a bit of late, and it always gets bad over the Bay of Bengal, guaranteed. Flying to BKK tomorrow and I must say, not looking forward to it. Absolutely heartbreaking 😢
She was quite rude, halfway intervene while he was talking.
Let him finish.
Glad most are safe.
Yup she confirms the reputation of CNA as not being lightweight news wise but quite dum at times. Sigh
LOL CNA is a sponsored U$ prop channel, they don't have real journalists only propagandists pretending to be journalists, just look at their past hit pieces!
the news anchor is so incoherent. what is happening
Where clear air turbulance can happen? Any certain geo location?
How do we know it’s not a defect with the plane or pilot error?
Alvin Lie excellent 👌
*Over 30 passengers injured is huge number and thats why seat belt is highly necessary during turbulence so need to find out hows the crew onboard adhere to this protocols during the incident*
Many of us fly SIA before. I am confident the crews did what they could to make sure passengers have their seat belts on. But they can't really force people without authority.
True, fasten seat belts at all times. But as the Clear Air Turbulence happened during lunch time when everybody is either eating, finishing lunch or going to the toilet, there is nothing to prevent them to cause injuries. By chance those seated with seats belts managed to escape and sustain less injuries than the rest... No fault of their own
Most times people ignore the crew when they tell them to put their belt on when seated I have seen people do that a lot of times in light turbulence, but this one was severe
It’s very well been explained. Listen again if you don’t understand.
The question is what are you doing here
Wow Indonesian analyst. So proud.
Extreme force of nature can strike any time. Life is full of unpredictabilities. The extreme turbulence was sudden, unpredicted, and violent.
Rest in Peace
He is a INDIVIDUAL AVIATION ANALYST, so this Mr Lee is not from SIA? He is speaking for SIA Pilot? Where did he get the info?
*Why cant the pilot divert the plane from flying into turbulence*
🇮🇱
People should be wearing their seatbelts at all time whilst seated, even on the toilet seat.
Toilet seats have seatbelts???
😂😂😂
Weather is very bad ever since this year, climate change that's why, nobody's fault.
Climate change has NOTHING to do with clear air turbulence. Just like rogue waves. Stop with this simplistic climate alarmist nonsense.
It appears we know little in the ambundance of wide and varied Air turbulences.
We cannot therefore detect,prevent and act against them
March 2024 - Dali Cargo Ship
May 2024 - SG Airlines
What,'s happening?😮
What are you suggesting?
So why does this not happen more often ?
SIngarpore airlines top of the line qualty accross the board there some things that are simply unavoidable.
I recall a Russian Airlines flight having severe turbulence over the Andaman Sea
Any flight crew never fail to warn about the known turbulance. As a passenger, I remain seated with buckle up all the time except using the lavatory.
Clear air turbulence is undetectable or unable in advance awareness.
Triple 7 is a beast I'm glad it wasn't a smaller aircraft.
Condolence whom family have been lost here ,with big in our heart,r.i.p,may god almighty ease whole passenger recover well better fast enough soon,honourly for all the be concern on the ground enhanced ,Thais medical aid and staff involved here now,thank you much alot for your concern priority for cooperation ER,unpredictable air technical error failure today,all passenger safety the first priority for all ingoing,the god almighty bless your all
Do not compromise safety when taking flight. As long as ur not going to toilet keep ur seatbelt on. Alot of pax dont care about this, tinkering their belongings, standing on the aisle , going to toilet frequently etc.
The news presenter is a bit thick... daft questions and doesn't understand what the expert is saying...
Upper altitude winds at the time of the incident were light, less than 30 knots, with no jet stream in the area. The likely cause was an encounter with a thunderstorm. Thunderstorms are common and were present in the area at the time of the incident. The flight can go from smooth to severe turbulence in an instant as the aircraft enters an isolated cumulonimbus. Onboard weather radar can display moisture in thunderstorms but occasionally it won’t display the upper parts of the storm where strong vertical winds are present without moisture.
"Upper altitude winds at the time of the incident were light, less than 30 knots, with no jet stream in the area. The likely cause was an encounter with a thunderstorm. "
If it's thunderstorm, either the weather forecast on route would have indicted or the weather radar on board would have shown.
The onboard radar don't just "see" a slice of what is ahead but a column of it, not to mention that the pilots can point it up or down to "see" more of it. With the colours, you kind of "cannot" miss it.
If the plane gets into the "upper parts of the storm", they would be in a sudden climb with the air coming up from below, instead of descending. Hot air rises and that is 1 of the 3 ingredients required for thunderstorm. The upper parts of the thunderstorm would likely contain more moisture as well, thus making it clearer for the radar, something like anvil cloud. Due to the temperature, the upper part of the cloud starts to spread.
@@user-yb1wt2mq8c Most of what you stated is correct. There were active SIGMETS for convective thunderstorms in that area at the time of the incident. There were no active SIGMETS for severe turbulence at the time of the incident. I fly Pacific routes regularly between Hawaii and Australia and occasionally in South East Asia. As a general rule you don’t encounter clear air turbulence in the equatorial regions, strong jet streams don’t exist there. Bottom line…on board weather radar is not perfect. We rely not only on the aircraft’s weather radar but on other sources of information including PIREPS ( weather reports from other pilots ), visual clues ( simply looking out the windshield ) or SIGMETS ( official weather warnings about inflight hazards ). Because there was a death and serious injuries this will be classified as an accident. I will be looking forward to the cause and contributing factors in the final report.
Can we call CHT for interview? His pay went up by how much?
That part of Andaman Sea @ parallel to Phuket & Langkawi is a hotspot for air turbulence especially for bigger aircraft, depending on the weather. Frequent flyers, experience pilot and cabin crew knows it. As precaution, better to fasten your seatbelt when flying over this area. It can happen anytime, to any aircraft.
The cabin.above the seats must havr opened as well.
Thankfully most passengers are physically ok but feeling traumatised. Hope they will feel better soon. Condolences to the family of the gentleman who died. Wishing speedy recovery to those injured.
🙏😞❤️I would like to express my condolences to those who lost their lives in this plane crash!🙏😞❤️
Alvin Lie if not wrong is Indonesian right?
Sounds like he's an Indonesian.
Why don't they just interview pilots rather than analysis and "experts".
Plan dropped 6000 feet in 3 minutes. Turbulance?
Clear turbulence not detectable.
7000 ft in 6 minutes is not a sudden drop. It appears to be a controlled descent of some nature, by the pilot or autopilot. Was there a loss of instrumentation being Boeing, since feed back is that the aircraft nosed up and down. Or did the pilots doze off and autopilot did the correction? Or did the pilots react with delay? Could be loss of instrumentation, 6 minutes is a long time!!! Plus food service was in progress.
Scary 😧
Was this a quick disclaimer video?
Not pilot, not aircraft. The video leaves lots of unanswered questions.
Had similar incidents happened in China 🇨🇳, no news!
Here comes the bot.
China would blame it on technologies developed by democratic countries... which they love to steal.
well. it's was not clear air turbulence. Radar did show extreme weather at the time, but the pilots did not deviate their course, nor did they slow the airplane appropriately.
A simple safety airlines addition could be a type of aeroplane ceiling light 🚦 much like when the pedestrian crossing lights are launched,where the plane ceiling light launches a 'Green light' to inform all those passengers that have an installed button on the arm rest,which is operated like a Bingo Light which informs the passengers who have pressed the button to use the toilet,when their turn to use the Plane Toilet- this will prevent any unnecessary queues outside the toilets and prevent any accidents as in the case of this London/Singapore turbulence death and injuries
I hate it that people got hurt and one person was killed, but every passenger should be mandated to wear seatbelt during the flight, except to go to the restroom.
For long haul flights, it's good to take a little walk to stretch the legs as well. Turbulence don't happen 100% of the time and don't happen in the whole flight, so best advice would still be to have the seat belts ON when seated even if the seat belts lights are off. Go to the toilet, take a short walk, etc as necessary, when seated, seat belts on.
So scary .. 😢😢😢always put your seat belt it’s for your on safety..
With technology getting improved, how come clear turbulences are not detected to take evasive action? Understand this particular aircraft Boeing 777 300ER over 10 years, could this be the reason for not having tge latest technological updates?
Currently there are no tech that can detect clear air turbulence or air pockets.
The weather radar on board depends on detectable moisture in the air [example clouds], sometimes there are moisture in the air but too low for the radar to pick up, so radar will show it's clear as well.
Humans don't fully understand about weather [we are still learning more about it] and how clear air turbulence, "CAT" [or air pocket for that matter] form.
Predictable turbulence like near thunderstorm, strong jet stream, large pillar of cloud/s building up, etc are avoided but you can't avoid what you can't "see".
Maybe go into the meteorological/weather industry to learn and help come up with a solution to "CAT" or air pocket.
1 thing is for sure, climate change is making these things worst and more frequent.
She is prompting him what to say...Her question is not even allowed to be answered and she already interjects with a suggestion...
sounds like microburst that pushes down the plane down 6000 feets.
A sad news ? Just as they announce a record breaking an almost 8 month bonus😢A bitter sweet year for the crew
I want to know how high were they flying before they dropped to 6000 feat.
According to FR24 37000 feet, normal cruising altitude
I think the decline was by 6000ft not TO 6000 ft
Unfortunately, I often can have a very good guesse after listening to welcoming announcements what our journey would like. I am sorry to say this, but some pilots from certain areas of the world fly much wilder than others
We don't if the pilot/Singapore Air made a mistake until the evidence is analyzed
There's more to this than meets the eye! Does Alvin Lie work for or derive income from this Airline? Was the aircraft a Boeing and what model? No one should be making excuses or covering up until a full investigation is made and released!!!
Wouldn't have anything to do with all this extra solar activity no? Worth keeping an eye on...
"solar activity" as in solar flare or climate change's heat?
If it's the latter, yes, climate change is making weather phenomena more frequent and worst. So there might be more clear air turbulence or air pockets happening.
Loss of 6000 feet alt in just under 3 minutes calls for either a monster wind sheer or mechanical defect😮
Have you watched the video?? 6,000 feet in about 5 mins [not 3]. The expert is making an educated guess that this was caused by Clear Air Turbulence [aka "CAT"] or maybe an "air pocket".
These things do happen.
I had similar experience during flight to thailand , not singapore airlines.
I forgot my seatbelt. I mean my friend saw me floating a few seconds. Lets' pray for all.
Please provide adjustable safety belts for plus size people too and for kids .
CAT Clear Air Turbulence Finally an expert it talking sense, at that FL there is no moisture, so no radar returns. The only possible warning is a sudden increase or drop in OAT Outside Air Temperature. FL = flight level = altitude above mean sea level. A global reference point all planes work to with high accuracy) In a seat? strap on....you are comfortable but your body is travelling at 300 Miles per hour!!!!
maybe add "FL, Flight Level" or use altitude/height instead since non aviation people might not understand what is flight level.
Please do not feature Alvin Liu/ Lee anymore. He doesn’t seem to be clear of the situation. He seems drunk commenting
Dear lady 🤦♂
