If it was a heart attack then why the descent? The airbus 320 does not have a control yoke that a slumping pilot could push forward. Either terrorism or suicide is my guess.
...”Either terrorism or suicide is my guess”...
Looks like it thus far. Just heard some flight people speaking about this and said hard to say otherwise just by the fact there was no mayday and that they have reported the other piolet tried to break down the door.
Shessh...can you imagine hearing this while investigating?....let alone being the other pilot trying to break down the door knowing well the plane was going down.
