Something (in italics) very strange is flying around at terrific speeds. Although no one has managed to --------> photograph the craft itself, its radar image, unique exhaust contrail, engine sound, and sonic boom have all been characterized in multiple reports by observers in the Western United States and Great Britain. Yet, questions directed to the prime suspect in mystery-plane cases - the U.S. Air Force - yield only denials of any knowledge. The aircraft, betraying its shadowy presence may be a high- altitude hypersonic spy plane code-named "Aurora" that's presumed to have replaced the retired SR-71 Blackbird (see "Revealed! Mach 5 Spy Plane," Nov. 88). On five occasions-> since June 1991, the U.S. Geological Survey's extensive network of earthquake-monitoring seismographs in Southern California has recorded window-rattling sonic booms produced by an airplane traveling northeast at several times the speed of sound. The booms have all occurred on Thursdays at about 7:00 a.m., says U.S. Geological Survey seismologist James J. Mori at the California Institute of Technology in Pasadena. "We call them airquakes," he says. "This mystery plane has a distinctly different sonic-boom waveform than other large--> supersonic aircraft like the space shuttle and the SR-71. "We track it because people have been calling us wanting to know if there's been an earthquake." Many observers in several states have reported hearing very loud, deep rumbling and pulsating sounds coming from an aircraft moving at high speed. An aircraft emitting these sounds was spotted this past February taking off at night from Beale Air Force Base near Sacramento, Calif. Its propulsion system may be a pulse detonation wave engine - a known type that develops thrust in intermittent bursts, ---> rather than continuously - according to reports in the trade journal Aviation Week & Space Technology. Bill Sweetman, an ecpert on classified "Black" military PRODIGY(R) interactive personal service 10/04/92 7:30 PM programs, suggests in Jane's Defense Weekly that the aircraft may be capable of reaching Mach 6 (4000 mph) burning liquid methane or hydrogen fuel. He believes the plane is returning from hypersonic (greater than Mach 5) flights over the Pacific Ocean and decelerating over the Los Angeles area as it heads northeast for a landing at the highly classified flight test base at Groom Lake, Nevada.--> Sweetman reports that a Royal Air Force air traffic controller tracked an aircraft leaving the remote NATO-RAF base at Machrihanish in western Scotland last November at a speed of Mach 3. No acknowledged aircraft capable of such speed is based there. See next note for conclusion of article.
