One dropped in at KSLC this evening. https://www.ksl.com/?sid=37407464&nid=1 ... d=topstory

I would have agreed with you. The test is contrived and the people know it is coming, so that should make the test invalid.

Well, until it actually happens for real.

After coming to rest, fire was noticed outside the aircraft, and an evacuation order was given. The two rear left exits remained closed due to the fire. On opening the emergency exits, one of the right middle exit slides (R3) deflated after being punctured by debris from the aircraft, while one of the left slides (L2) failed to deploy at all for unknown reasons. A number of passengers were forced to jump from the aircraft to exit. The actions of the flight attendants, who ensured that all of the passengers quickly evacuated, contributed to the safe escape of all passengers. The first officer was the last to leave the plane, which was evacuated within the required 90 second time frame.

This was not expected, plane was on fire, plane was damaged, some exits did not work, plane not on level ground, embedded in trees, at night, in heavy rain, with tired passengers from an 8 hour flight.

All in under 90 seconds.

Can't be any better validation than that.

Just did the LA-Sydney flt last week on a Delta 777. That was 14 miserable hrs. Not an empty seat. Already dreading the return trip next month.
