Investigation into Virginia Plane Crash Begins Amidst Sonic Boom and Fighter Jet Sightings.

NTSB investigators are examining the wreckage of a Cessna Citation that crashed in Virginia after being intercepted by F-16 fighter jets due to a loss of communication with air traffic control. The pilot, Jeff Hefner, was a retired Southwest Airlines captain and experienced aviator. The crash site is in a difficult-to-access area, and it is unclear whether the plane had voice and data recorders. The cause of the crash is still under investigation, but experts suggest the plane may have lost pressurization, leaving the pilot and passengers unconscious. The victims have not yet been positively identified.
