Officially, UA93 crashed into the ground near Shanskville, PA at 10:03am (or 10:06am) in an inverted position (belly up) at a 40 degree nose down angle. The plane's position is from the official report apparently obtained from the flight data recorder.
Officially the plane crashed, and went into the ground leaving a plane-shaped crater and no large debris on the ground. No tail section, no wing section, no fuselage section was found near the crash site, in contrast to the vast majority of plane crashes.
Here are some pictures of the flight 93 crater--
Using these pictures of the flight 93 crater, William Seger has created some diagrams that not only show how ridiculous the official story is, but also PROVE a Boeing 757 cannot have crashed into the ground and produced the crater that was found near Shanskville--
Here I added some text to his diagrams, to help explain what he shows--
Here is my cruder diagram that also makes the same point as William Seger's diagrams:
