For anybody else who is wondering if this would always go so smoothly in a real emergency: http://www.flightglobal.com/news/articles/do-aircraft-evacuation-tests-work-315093/ http://www.flightglobal.com/news/articles/do-aircraft-evacua...
Some notable points from that article:
Trials assume that passengers have no friends/family on board and further ignores the presence of passengers with disabilities
Full-scale evacuations [tests] remain a costly headache at around $2 million, not to mention the risk of litigation when things go wrong. While most common injuries to volunteers range from cuts and bruises to broken bones, the industry is haunted by the McDonnell Douglas evacuation certification trial for the MD-11 in October 1991 when one volunteer was left permanently paralysed.
In one real life 737 crash, the last passenger came out 5.5min after the burning aircraft had ceased moving, while in the 737 certification trial, the entire load of passengers and crew evacuated the aircraft in 75 seconds.
Under the current "make or break" single-test regime, the aircraft will pass as long as the result is below the 90 second threshold and it is argued that the current procedures are designed with the sole purpose of passing the test - even if that does not necessarily mean they will work in real situations.
Certification based on a combination of computer simulation and real world testing is suggested as a way forward.
- ams6110 12y agoA big problem with real emergency evacuations is that passengers try to take their carry-on luggage with them.
- tmd83 12y agoI see a lot of people jogging smoothly forward which is not going to happen. And beyond disability just not everyone being as fit and bouncy like the video will slow things down a lot. The speed of a passengers through a particular exit will not be average speed of the passengers but the slowest one out. Also the confusion, trying to get ahead in fear that will surely contribute. There are also likely to be people who are inexperienced flier or haven't thought about how important it is to evacuate orderly or hadn't really listened to the instruction. For countries like mine where orderly lines or safety drills are not really practiced it will only be worse. I find 5.5 min surprisingly good even if it should be better.

- ohashi 12y agoI can see people banging, waiting, pulling, struggling to get them open anyways and blocking even more people from getting out in a real world scenario.
