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.
Either way, you shouldn't ignore the stewardesses' advice. This training is always done on board aircraft to be freshly imprinted in the memory of passengers. But many of them are also on the internet. US Airways made an emergency training video for Boeing 757. You know the saying, "rehearsal is the mother of learning"!
