"After reading down through the bottom of the Flight 93 page, this quote may suggest that the passengers may have actually managed to re-take control of the plane and bring it out of it's dive, but not quite in time.
If the plane dove straight in at the speed given, there would have been no re-bounding of the plane or plane parts, I don't think. The quote shows that part of an engine landed 300 feet from where the plane augered in. I'd guess it was beginning to level off after the passengers dispensed with the highjackers/suicidal-homicidal crazies before it crashed and the engine fan hit at an angle that would allow it to bounce and continue forward after first impact. Just a guess.
"Jeff Reinbold, the National Park Service representative responsible for the Flight 93 National Memorial, confirms the direction and distance from the crash site to the basin: just over 300 yards south, which means the fan landed in the direction the jet was traveling. "It's not unusual for an engine to move or tumble across the ground," says Michael K. Hynes, an airline accident expert who investigated the crash of TWA Flight 800 out of New York City in 1996. "When you have very high velocities, 500 mph or more," Hynes says, "you are talking about 700 to 800 ft. per second. For something to hit the ground with that kind of energy, it would only take a few seconds to bounce up and travel 300 yards." Numerous crash analysts contacted by PM concur."

I don't think so, eye witnesses claim it went inverted and crashed out of sight. If it hit inverted, that would explain the engine being thrown away from the wreckage.
