with the intention of using it later for another purpose.
Sadly with the emergence of the mad professor that is what I believe. I think we are in ACT 1. Sadly that theory encompases everything. The terrorist group, the plane involved in an ER model (extended range), inability to find ANYTHING = plane is on ground safe and sound and ready for whatever mad proff has in store.
The intial story that the airline lost contact not ATC is huge. With the emergence of the proff I believe that the aircraft WAS in contact with the airline (not ATC) on the back channel with demands.
The military tracking "escapade" fits as well. He stated it , makes sense that there would be military tracking. THen, hours later he totally is PRESSURED to say he did not say what the world heard him say!
Obviously the terrorist group linked to professor is in a very very bad mood the past several weeks. To go into a public place and start hacking people to death certainly indicates a group with some "issues".
