shit dude, i dont have time to watch these videos... you shoulda been here 5 years ago when this shit was actually discussed.
anyway, pop mech went on a radio interview and claimed that the fbi had DNA from all 18 hijackers, 24 hours after the attack - that's how they knew who they were. Go find the 18 minute radio interview with the pop mech guys. It was discussed here in depth.
They were asked how the dna was recovered from the towers which were still receiving water hoses at that point - how in the worl they were able to sort out DNA that fast... and they didn't have answers.
they're some non-credible fvcks, in my own opinion. Find that interview and listen. Now, I dont have time to argue point by point with anonymous engineers here... but if you listen to that 18 minute owning of the pop mech guys... i mean, they get cornered so many times, it's insane. They made some of their shit up, plain and simple.
plus the eitor was mike chertoff's cousin...
so anyway, if you want to give them credit, at least here them caught in lies in that radio interview. good times.
