well , if one of the door is opened, and you continued, a pax was suck out of the cabin in the air and
. after this happened, someone will ask you why didn`t you abort. i know the door open light most of the time is a faulse alert, but what if it`s really opened, do you think it`s a great risk?
Somebody will always ask afterwards, "what if"
You can't go wrong if you protect the aircraft first. It's sure to save more lives that way.
