I am no pilot, but the dives he was in and rolled out of seemed a little above the Flight Simulator grade of flying.
Can a pilot give us a sense of that?
This whole thing sounds fishy.
He'd be following in the footsteps of Mathias Rust flying into Red Square, the guy that flew a Cessna onto the White House grounds, the Bishop/Bishara kid in Texas that flew into a building and the mysterious MH370 pilot, among others.
(My conscience is clear regarding 9/11, however.)
