With a suspect with a name like that, am I suppose to surprised??
I was an inspector for the Boeing company, in the 1960's, on a final assembly line. Trust me, anyone with my experience, or the mechanics I worked around, wanting to bring down an airplane, it would be a done deal!!!
You don't need some suicidal nut job with a gun.
Also, consider the outcome of Flight 93, or any of those other flights on 09-11-2001 ,had one of those brave people had a gun!!
Additionally, all of those planes were well below 10,000 feet when the SHTF and a bullet through the side wall would have little effect!!
