Sounds like the co pilot had plans.

Reminds me of EgyptAir Flight 990!

[cherry]

the report is that they heard the two pilots talking normally then one of them left the cockpit and then could not get back in...they heard gentle tapping and then louder more urgent pounding on the door...

the pilot in the cockpit could have suffered a severe medical emergency OR he could have meant to lock the door and had terror on his mind...

do cockpit doors automatically lock?

if they heard the talk and the tapping, then they must have a time associated with it I think...so they could match that up with the start of the descent...
