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 dont 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.
The more I think about it, I'll also conclude a 'suicidal' pilot did it, more specifically the PILOT SITTING ON THE RIGHT SIDE OF THE COCKPIT (Which Mohammed was that?) We all know he REALLY did it for Allah, though. The media can't wait to call it "SUICIDE" and bash Trump for blaming terrorism.
This. If these sensors showed that the problems were only in the front of the plane, and Shoebat found the pilot had friendship with terrorists, he may have brought the bomb on board.
