Military officials in Massachusetts say they've confirmed that the pilot of an F-15 jet that crashed in remote Virginia mountains was killed.
Colonel James Keefe says his "thoughts and prayers are with the family" of the pilot, whose identity hasn't been disclosed.
The pilot and jet were with the 104th Fighter Wing of the Massachusetts Air National Guard.
The F-15 fighter jet crashed in the mountains of western Virginia on Wednesday, shaking residents but causing no injuries on the ground.
Authorities said the pilot of the single-seat jet was headed to New Orleans for radar installation as part of routine maintenance and reported an inflight emergency before losing radio contact.
