Haven’t read the whole thread and I suspect this may have been mentioned already, but the location given in the news video is very close to San Nicolas Island, where Boeing has a launch facility for missiles for Airborne laser tests...
EDWARDS AIR FORCE BASE, Calif., Aug. 13, 2009 — The Boeing Company [NYSE: BA], industry teammates and the U.S. Missile Defense Agency on Aug. 10 successfully completed the Airborne Laser’s (ABL) first in-flight test against an instrumented target missile, achieving a historic milestone.
During the test, the modified Boeing 747-400F aircraft took off from Edwards Air Force Base and used its infrared sensors to find a target missile launched from San Nicolas Island, Calif. The Boeing-developed battle management system aboard ABL then issued engagement and target location instructions to the beam control/fire control system, which acquired the target and fired its two solid-state illuminator lasers to track the target and measure atmospheric conditions. ABL then fired a surrogate high-energy laser at the target, simulating a missile intercept. Instrumentation on the target verified that the surrogate high-energy laser hit the target.
Now that would make sense....but would think there would still be a NOTAM that would have to have been filed...
