In the article "In Plane Sight?" which appeared in the Washington City Paper on J(p.12-13), one of the seismologists, Jim Mori, noted: "We can't tell anything about the vehicle. It is not definitively known if these events can be tied to the Aurora program or to other acknowledged or secret programs. Furthermore, neither the shuttle nor NASA's single SR-71B was operating on the days the booms were registered. Seismologists say that the sonic booms were characteristic of a smaller vehicle rather than the 37-meter long shuttle orbiter. ![]() ![]() The aircraft's flight path was in a north-northeast direction, consistent with flight paths to secret test ranges in Nevada. Seismologists estimate that the aircraft were flying at speeds between Mach 5 and 6 (3,300-4,000 mph) and at altitudes of 8–10 km (26,200-32,800 ft). The incidents were recorded in June, October and November 1990, late January 1991, and in mid 1994. Geological Survey sensors across Southern California used to pinpoint earthquake epicenters. On at least five occasions, these sonic booms were recorded by at least 25 of the 220 U.S. A series of unusual sonic booms were detected in Southern California, beginning in mid to late 1991. ![]()
