Two unusually Loud Sonic Booms heard along the West Coast from San Diego to north of Las Angeles may have been produced by Super Secret USAF aircraft returning to test ranges in the Nevada desert. Twenty Five of the US Geo Survey's Earthquake detectors have been set off after detecting loud bangs or explosions above 23,000 ft. The sonic booms where 100 seconds apart and are confirmed to not be the shuttle, Fighter or Bommer aircraft of missiles being destroyed.
