As for your questions, I am not a pilot, nor an expert in aviation, and neither am I a structural engineer - and neither are you. One thing I would say though - if there was a qualified pilot who was under threat aboard a plane, I don't believe it would be too difficult for a terrorist with 6 months training to guide it to its target. Additionally, if there were explosives in those buildings, which is what you have suggested in the past, and which is what I presume you are suggesting now, my impression would be that Muslim terrorists working in those buildings placed them there and detonated them at the appropriate time. That wouldn't have been difficult in a time before security was so keenly employed prior to 9/11.
Keyplus, you never cease to disgust me. You deny that Muslims are responsible for the terrorist attacks, for the murder of innocent hostages such as Ken Bigley, or for any of the other related atrocities we are now seeing in this world; you advocate the murder of people who criticise your prophet, and you offer 9th century anecdotes to illustrate your antiquated thought processes. Well, we are living in the 21st century, not the 9th, and you and the people who think like you are, in my opinion, not only an ever-increasing danger to the rest of humanity, but a complete blight on this world, and a total disgrace to civilised society. Birdie used perfectly appropriate wording for this question - 'the religion of peace shows its true colours.' You've certainly shown yours.
