I believe this is a big misunderstanding that has snowballed recently. I think what he actually claimed was that he did all of these outrageous stunts in a network simulation that he had, not a live aircraft. That is why he has not been arrested. He wants publicity for the issue of security of aircraft computers and that's why he isn't rushing to squash these "I made the airplane do a barrel roll" stories.

What's better for raising consciousness about a potentially fatal flaw that by making people think that lives were at risk when they weren't?
