dumb airplane question

[MelchyBeau]

I have never heard of this before either. Though I rarely pay attention to what they are saying.

however google is your friend in this. Section G

It seems to deal with the possible need for an emergency evacuation of the airplane. more windows open will mean easier to see where you are going.

if the windows are open the passengers will not be blinded when the fuselage rips open and you have to get out

also, when the plan inevitably crashes and bursts into flames, the ground crew is better able to look into the plane to figure out who needs some saving.
