I don't know what to say. Those old fellows just laugh their arses off at the prospect of anyone swallowing this stuff.
Then they need to go pay tribute to those patriots at the site, for themselves, and talk to the locals who man it.
Your old buddies share the same world perspective as ignorant people all over the world, like the muslims who ululate in the streets when Jewish or American children die.
BTW, my brother hangs out with guys like those you mention at "the home"...he is an EMT in western PA and HAAAAATES Pres Bush. If anyone knew there was some kind of conspiracy it would be the EMT's and it would surely be guys like my brother.
He did not respond to the crash scene but had friends who saw the plane flying low and erratically about 15 minutes before it went over the first crest of the Laurel mountains and then drilled into the ground at about the 3000 foot elevation, probably because as evidence shows, the hijackers tried futilely to use aircraft motion to throw the passengers off their feet and then pushed up the throttle as the plane went down...inverted, at 560 kts.
