In Feb 2016, a laptop bomb was smuggled aboard an Airbus A320 in Somalia. A passenger set it off, blowing a hole in the side of the plane that sucked them out. Despite the damage, the plane managed to land.

The Egyptian A320 was in Eritrea (near Somalia) the morning of the crash. Maybe the pilot picked up a laptop bomb and carried it aboard. They don’t check pilots that thoroughly.
Sensors on the Egyptian A320 showed smoke and things failing in the cockpit and nearby restroom. A suicidal pilot could have brought a bomb on board.
and I checked headline before I posted and did not find anything..........maybe I am doing searches wrong. sorry
