So makes perfect sense that if the pilot in the cockpit were having medical issues, he would turn around and lock the door so no one could get in. /sarcasm
Looking more and more like a duck.
No...it is SOP to ALWAYS lock the door...again the question is why no flight attendant in the cockpit?
Do the doors auto lock? I don't know.
BTW, the pilot could have locked the door, and then had a massive heart attack. In that case the pilot would be totally incompaciated.
They need to find or reveal what the flight controls were set at when the pilot exited the flight deck. Were they subsequently changed?
Exactly what I was thinking.
