Claim: One of Flight 93's engines was found "at a considerable distance from the crash site," according to Lyle Szupinka, a state police officer on the scene who was quoted in the Pittsburgh Tribune-Review. Offering no evidence, a posting on Rense.com claimed: "The main body of the engine ... was found miles away from the main wreckage site with damage comparable to that which a heat-seeking missile would do to an airliner."
FACT: Experts on the scene tell PM that a fan from one of the engines was recovered in a catchment basin, downhill from the crash site. 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.
