Member of 1946 elite secret military crash team describes UFO search, crash scene, and field test on sample

I have interviewed an expert witness to a UFO crash. This person was a member of an elite, secret, military airplane crash team in the 1940's. The team investigated several airplane crashes. Then, about 6 months before the Roswell event, this crash team was ordered to race by land to a crash scene in a mountain wilderness area. The team had to force hike into the crash site.  The hike consumed the better part of 11/2 days since it was extremely difficult to find the crash site. Once discovered, it was quickly obvious that something had slammed into the top side of the mountain, and %100 exploded into thousands of palm sized pieces which were strewn all over the forest floor. My witness picked up a sample and conducted simple field tests on the strange object. The tests defied the known laws of engineering and physics.
Original report Description follows:
1940's secret, elite military crash team member  reveals  another UFO crash  event  months  before  Roswell
My witness is a former crew chief who in the 1940's was in charge of a team that  repaired military fighter airplane engines at a famous military airbase. The crew specialized in fast engine repair. My witness was also a member of a secret military airplane crash team. This elite crash team was always on alert to speed to a disaster either by air of ground. The team was composed of civilians, enlisted men and officers. My witness became experienced in airplane crashes. He knew what to expect, what to look for, what to do upon arrival at a crash scene. At this particular crash, it was quite obvious that the craft had slammed into the side of a forested mountain and blew up into thousands of small objects scattered over a large area. Field tests revealed startling results. A shroud of secrecy settled. After that came Roswell.
