And at least a little sarcasm. Check out this post from Telstar Logistics, describing a recent test of Airbus evacuation employees. This test was done with Lufthansa employees, without smoke, fire, or other conditions which – assuming an emergency evacuation in the first place, would seem to be within the real of possibility.
How long would it take for everyone to get off the A-380?
In a best-case scenario, with no smoke, no fire, limited structural damage to the aircraft, and no one who sustained any injuries during the landing, it would take a little under 80 seconds to evacuate 853 passengers and 20 crew members from an A380.
…. even under those most ideal of circumstances, there were casualties: one broken leg and 32 friction burns.
It’s clear that the thing to do is just make sure that bad things only happen during ideal conditions.  There’s also a link to a YouTube clip of the evacuation exercise – and an even more disturbing bit from the Wall Street Journal about a McDonnell Douglas evacuation exercise.
