Sorry if this has been posted before, I haven't got time to go thru the voluminous posts
I've been playing around with Google Earth and found something very interesting. If you pull up the location of the Shanksville 'crash' apprx 40 03' 03" N lat and 78 54' 17" W longitude (there's pictures posted of the memorials and it will soon become apparent of the correct location); you can somewhat see the 'scar' in the earth, there's what looks like two irrigation ponds nearby and a handy-dandy rather hidden road going up to the back end of the exact spot of the crash.
Okay, now take a look at the top, there's an icon with a clock face on it; slide the clock to 1994 and take a look. Big huge gouge in the earth at the exact same spot of the later purported crash, and just near that, an artificially created berm that could only have been created by machinery and looks like it would be very effective to block the view of the 'crash' site from road.
It doesn't look like the purported potato field or whatever the hell it was supposed to have been. Looks like a prepared dump site. Back in 1994.
Just wanted to thank everyone for all their work on this site. Good stuff and it helps every time someone calls me a lunatic to send them over to the aeronautic pros.
