US Airways presents emergency training to Boeing 757
When boarding a plane, regardless of its type, it is always a flight attendant who gives you emergency training. It differs from aircraft to aircraft. Those who travel a lot by plane are likely to have come to dream of these instructions, and those who will fly for the first time will probably be surprised at what will happen.
In any case, you should not ignore the advice of stewardesses. This training is always done on board the aircraft to be freshly embedded in the passengers' memory. But many of them are also on the Internet. US Airways made a video with Boeing 757 emergency training. You know how to say: "repetition is the mother of learning"!
