The controllers could not identify the plane because apparently someone on board had turned off its transponder--the equipment that sends the plane's airline, flight number, speed and altitude to radar screens. Tentatively, the plane was identified as American Flight 77, which had been scheduled to take off from Dulles at 8:10 a.m. for Los Angeles, with two pilots, four flight attendants and 58 passengers on board. The skill with which the plane was flown, including the knowledge of how to turn off the transponder, raised the probability that a trained pilot was at the controls, possibly a hijacker. Sources were not specific about the times of the events, but said that after leaving Dulles, the plane continued west for a while. At some point, apparently after turning off the transponder, the plane turned back toward Washington with no radio contact. The plane would have appeared on radar screens as an unidentified blip called a "primary target" something commonly seen by controllers when an aircraft does not have a transponder or is a military aircraft flying with its transponder turned off. However, the airspace around Dulles, Washington Reagan National Airport and much of Washington is designated "class B" airspace, meaning no one is supposed to fly there without a working transponder and permission from a controller. The sources said Dulles controllers noticed a fast-moving primary target in their airspace east-southeast of the airport where it shouldn't be, headed directly toward the restricted airspace around the White House. They called controllers at National Airport to tell them that an unidentified unauthorized aircraft was headed their way. However, as they watched, the plane began turning to the right away from the White House, circling a full 270 degrees to the right and approaching the Pentagon from the Southwest. It then dropped below radar level, disappearing from the controllers' screens, shortly before hitting the Pentagon about 9:30 a.m., less than an hour after two other aircraft hit the World Trade Center towers in New York City. Federal aviation rules limit the speeds of commercial aircraft flying below 10,000 feet. The sources said it appeared this plane was at full throttle. Controllers then saw that a Boeing 757 identified as United Flight 93, flying from Newark to San Francisco, had turned toward Washington over Pennsylvania. However, the United plane crashed for unknown reasons about 10 a.m. about 80 miles southeast of Pittsburgh. Federal aviation officials are reporting that the transponders had been turned off on all four of the planes that crashed today, including two that flew into the World Trade Center. © 2001 The Washington Post Company ------------------------ Yahoo!
