near 90-deg angle" going
580 mph:
► Crews Begin Investigation Into Somerset County 757 Crash
"The plane then made a sharp, 90-degree downward turn and crashed.
Officials said that they believed that the plane took a dip and nose-dived into an abandoned strip mine.
WTAE-TV's Michelle Wright toured the crash scene and said that
a crater of about 30 to 40 feet long, 15 to 20 feet wide and 18 feet deep was created by the crash." - The Pittsburgh Channel (09/11/01)
► Cell calls from planes reveal horror
"At 10 a.m., the plane suddenly went down, crashing into rural western Pennsylvania, where it created
a crater 30 feet across and 20 feet deep, and scattered debris for half a mile." - MSNBC (09/12/01)

757 wing span = 124 ft

Crater length = 30-40 ft

Oh, and the entire plane supposedly swallowed up by the ground:
► Small town shoulders a nation's grief
"The site had been mined for coal,
then refilled with dirt. It was still soft when Flight 93 crashed, and firefighters said
the Boeing 757 tunneled right in.
They had to dig 15 feet to find it." - St. Petersburg Times (09/10/03)
So, how could a plane with a 124 ft wing span crashing "near 90-deg" only cause a 40 ft wide hole in the "soft dirt"?(And where did the tail section go???) 

Maybe this eyewitness at the scene knows:
FOX News reporter:
It looks like there's nothing there, except for a hole in the ground.Photographer Chris Konicki: Ah, basically that's right. The only thing you can see from where we where, ah, was a big gouge in the earth and some broken trees. We could see some people working, walking around in the area, but from where we could see it, there wasn't much left.
Reporter:
Any large pieces of debris at all?Konicki:
Na, there was nothing, nothing that you could distinguish that a plane had crashed there.
Reporter:
Smoke? Fire?Konicki: Nothing. It was absolutely quite. It was, uh, actually very quiet. Um, nothing going on down there. No smoke. No fire. Just a couple of people walking around. They looked like part of the NTSB crew walking around, looking at the pieces..."
