The planes that were in the works to blow up over the Atlantic would have made it so the passengers, "just magically disappeared". In the book of Revelation, "people will just magically dissappear". This makes it abundantly clear that Ahmy thinks he's a doomsday prophet. Whether his efforts are real or fabricated does not matter. He believes in his invincibality and most of the rest of the Islamists/and,or Muslims are just as nuts as he is, or he has them scared senseless. He will do whatever it takes to make the world believe, "he's the one to be worshipped"...
I agree....the man is clearly nuts.....crazy enough to do anything! Whether he will be successful or not remains to be seen, but I don't think anything will keep him from trying! And though they've slightly lowered the alert, I hear there may be many many more involved in the plot that they are looking for.
