It is initially reported that Flight 93 was traveling fairly slowly when it crashed on September 11. Days after the attacks, the New York Times reports that Flight 93 “slammed into the ground at a speed that law enforcement authorities said might have approached 300 miles an hour.” [New York Times, 9/14/2001] Another newspaper reports, “Flight 93 slammed into the earth nose-first at over 200 mph, according to estimates by the National Transportation Safety Board and other experts.” [News Journal (Wilmington, DE), 9/16/2001] However, by 2002 it is being reported that the plane crashed going nearly 600 mph. [Longman, 2002, pp. 212] “It could have even broken the sound barrier for a while,” says Hank Krakowski, who was United Airlines’ director of flight operations on September 11. [New York Times, 3/27/2002] The design limits of the plane are 287 mph when flying below 10,000 feet. [Longman, 2002, pp. 208]
