Exactly Balus, they all got out.
But now starts the period where people sit around in chairs drinking coffee with the sole purpose of second guessing the crew. It happens everytime. Maybe they shouldn't have evacuated, we don't know, but they did!! And they are all alive.
I still remember the Saudi L-1011 rolling down the runway with people unable to get out and dying as a result of it.
If all the crew had was an indication of a possible problem in the cargo hold I don't envy them. You have to make a decision based on very little information. I would have done the same thing, better safe than sorry.
