I wonder how is it possible that there could be people that doubted that it was a terrorist act ... As I wrote immediately after the first news :
STATISTICS IS a science

And for the same reason any one should be able to see that 9/11 was a work of the government.

Well the fact that the tail section on one plane was found 700m from the rest of it, definately indicated some type of explosion.
