Jabal, dorosenco, et. al., I am not, in any way, implying that all Muslims are suspect.
Various Muslim extremist terrorist groups have used suicide attacks against various targets. These have occurred in the US (Sept. 11), Yemen (USS Cole), Israel, Afghanistan, Iraq, Russia, etc. If those extremist groups have been able to convince followers to commit suicide before, why are we to assume that they could not convince a pilot to do the same?
I am unaware of any Christian group using such suicide tactics.
