"I believe all the passengers are dead, if even a few of them were alive they would talk if there was a conspiracy to talk about."
Okay John. Please continue with this line of thought - back up to before WTC7 came down?.
I saw the footage of planes hitting the twin towers, there are theories that another type of plane hit the towers(eg military plane) I don't really know, and when I don't know something I say so, but in my opinion it is more likely it was a commercial plane and people onboard died, bet we will never know so I don't waste my time on that unprovable stuff.
Do you believe they were commercial airliners that hit the WTCs?
I would say more likely yes than no, but no way to prove it definitely.
Unlike detonating a building, there is only one way to do that so precisely.
If not, how/where do you think the passengers died?
I really don't know, there are all sorts of theories, I think they are definitely dead and not living some secret lives somewhere, that just seems totally ridiculous to me and no way to prove anything like that so a waste of time.
