The FAA response is worth a read - <a href="http://files.constantcontact.com/7a85813b001/d1d4f4f1-9864-46a2-a056-69180fe2f2ed.pdf" rel="nofollow">http://files.constantcontact.com/7a85813b001/d1d4f4f1-9864-4...</a><p>The initial aspects that FAA talks about around evacuation safety makes sense - regarding the timing to exit in various situations.<p>However the next part, regarding panic, makes less sense to me.<p>> The FAA and other civil aviation authorities have conducted research testing to assess the effects of "panic-like" behavior during evacuations. These tests simulate the urgency of panic by offering passengers a financial incentive to be among the first out of the emergency exits.<p>Humans react differently to financial incentives than they do to life threatening situations. I do not see how offering money was a sufficient substitute to test panic-like behavior during evacuations.<p>The FAA response also mentioned videos included in the 'docket' - one of the videos can be seen here: <a href="https://www.youtube.com/watch?v=ns-em4utMSw" rel="nofollow">https://www.youtube.com/watch?v=ns-em4utMSw</a> - from which it's easy to see response times and the nature of these evacuation demonstrations. The volunteers appear to be quite relaxed and prepared for an evacuation.<p>Though I wonder why there is a group of people entering from the rear of the aircraft, is that the next batch of volunteers or is this a double decker aircraft? I have never been on the top part of such an aircraft so I don't know if there are additional exits up there.
