I understand UALover7 is aged 16 or something, so whilst I share a little of his youthful concern, do not feel posting a ream of uncorroborated speculation helps anyone at this time.
I do not believe the alleged case of a plane being hijacked and flown into the Eiffel Tower is anything other than baseless bar-room rumour. Unless someone can post a REAL link to some facts I think it is baloney.
