BURLINGTON, Vt. (AP) — The families of eight U.S. military men who died in a 1944 plane crash in the Himalayas want the Pentagon to step up efforts to recover their remains from the crash site discovered last year by a mountaineer.

Exactly what happened to the B-24 bomber, dubbed "Hot as Hell," was a mystery for more than 60 years. It disappeared while on a flight from Kunming, China, to Chabua, India, to pick up weapons and other supplies and return to base in China.

Clayton Kuhles of Prescott, Ariz., a mountaineer who has made it his mission to search out crash sites along a route so deadly pilots called it the aluminum trail, found the wreck last December near Damrah, a village of 200 in northeastern India.
