A Boeing 777 plane suddenly got into the zone of strong turbulence before starting to descend

CAT - Clear-air turbulence is usually impossible to detect with the naked eye and very difficult to detect with conventional radar, with the result that it is difficult for aircraft pilots to detect and avoid it.

Regardless of if the seatbelt sign is on or not it is always reccomended to keep it fastened and not get up unless for the toilet just in case they hit any unexpected turbulence, and this is exactly why.

Keep your seatbelt fastened. Why do people always think they know better. They only have themselves to blame

Now people realise why the weight of bags in overhead lockers is so important. You will notice people with a heavy bag never stow them above their own heads. There is a legal maximum and it should be enforced, not ignored by the airlines. The pilot CAN refuse to fly them.

Dreadful as this is - You are always told to keep your seat belts on and they must be in view over your blankets whilst sleeping!!

The mind boggles! What the hell were passengers thinking, in the they left their seats? Turbulence is only one reason why you wear a seat belt. Bloody fools.

Stupid not to lease seatbelts fastened when in seat.. REALLY stupid.

thats why i always keep my seat belt on! i loosen it but on!

I wonder how many did not have their seat belts fastened???

Well done to the pilot for getting the plane through this. Pilots can not alter the weather

Very sad, but despite there being a no seat belt warning at the time, all planes clearly announce that if seated it is advised that you always keep your seatbelt on at all times when seated. Juse in case. Might not happen but when it does this happens.

For those saying it's their fault as they had no seatbelts, some of the injured were walking (possibly toilet) in the isle. You can't have your seatbelt on at all times.

No sat belts?

There seem to be a lot of incidents like this lately. I attended a course to combat fear of flying and they told us that commercial airline pilots are trained to fly around severe weather, even though the airplanes can take the abuse. It's because it would be too uncomfortable and frightening for normal passengers. Apparently mail or freight planes usually just fly through bad the weather, because those on-board are trained to cope with the severe turbulence. I wonder if, in an attempt to save fuel, commercial airlines are now opting to fly directly through severe weather regardless of the impact on passengers? Providing the craft survives, I can't imagine they'll lose much sleep.

thank goodness the planes construction was strong enough to withstand what was obviously a violent disturbance.let us hope that those injured will recover from the terrible experience.

If you aren't moving around the cabin, you should have your seatbelt on at all times. What a terrible thing to happen.

This is exactly why pilots are always belted. Clear air turbulence cannot be seen nor detected. The only heads up is when another aircraft gives a turbulence report in the same vicinity. On routes that are more remote with less traffic and you are out there essentially all alone, you are taking a big gamble as a passenger staying unbelted.

Um, seat belts?

I've always kept my seat belt fastened

Unfortunately Russians love to ignore seatbelt instructions. It seems to be a cultural thing, they hate driving with them too
