At the time of take-off - although I do not pay much attention to flight attendants - sometimes I wonder why they explain to us in detail how we have to use the lifejacket in case of a plane crash and I think ...
A plummet to the sea at more than 600 kilometers per hour is something like crashing into reinforced concrete: Dead.
I have no record of any successful landing that has been made on water by a passenger plane: All dead. If anyone knows of any, it would be nice to tell us.
So I only have one conclusion left that can convince me why so many explanations to put on the happy vest:
To be able to easily find the bodies on the sea.
Sometimes it is better not to spin the head too many times. Anyway, let's hope it doesn't happen and have a good trip!
