Massachusetts Air National Guard F-15

The pilot of a Massachusetts Air National Guard F-15 is still missing after yesterday's crash in the Shenandoah Valley. Officials called off the search at midnight, although efforts were resumed at 8:00 AM this morning, Military Times reports.

The unidentified pilot, part of Massachusetts' 104th Fighter Wing, took off from a base in western Massachusetts, en route to New Orleans for an equipment upgrade. According to officials who spoke to Military Times, the pilot was in touch with the FAA and was flying at 30,000 to 40,000 feet before the crash, which one official rightly called "pretty high."

While finding an American pilot on the country's east coast might not seem like an actual problem, the rugged, mountainous terrain where the single-seat fighter went down makes radio communications difficult, according to Jalopnik's Code 3 blog.

Local, state and federal authorities have joined in the search, while crews have enlisted the aid of rescue helicopters and an HC-130 search and rescue plane in a bid to find the missing pilot.
