Read More
  • November 20, 1952 the USMC Sikorsky HRS-2 BuNo 129049 crashed during the recovery of microwave transmission equipment from a mountain top in the Mojave National Preserve. The accident happened as the pilot was attempting to land on the peak, but came up short due to heavy winds and downdrafts. The tail rotor struck a tree and rocks and was broken off causing the pilot to lose control. After crashing to the ground, the helicopter rolled about three hundred feet down the slope before coming to rest on it's left side. Luckily pilot Maj. Dwain Lengel, co-pilot Capt. Gaylord Drutknecht and the two passengers weren't injured in the accident. The HRS-2 was fairly intact and did not burn after the accident, but due to it's remote location the military decided to blow it up instead of attempting the difficult recovery. The HRS-2 was one of two US Marine Corp heavy duty helicopters provided from the Squadron 363 of the 36th stationed at El Toro, California. The microwave equipment was installed on four peaks by the Los Angeles television station KTLA to relay the first telecast of an atomic bomb blast from the Nevada test site seven months earlier on 4/22/52.

  • Driving in the Mojave National Preserve. About a year ago I saw a post about a group of folks that visited this site, looked interesting so put on my to do list. I was given it's location, but somehow I misplaced the information. I remembered where the hike started and had a good idea which area the crash site was located in.

  • This is where to road turned to 4X4. Knew where I wanted to go, but wasn't sure that this was the right way to get there.

  • The truck parked in a clearing at the top of the road which drops off to the left. The drive was a little nerve racking, felt good to get out of the truck and start hiking.

  • On the hike, I passed by a few prickly pear cactus. Took the time to snack on one of these before hiking on.

  • When I got into the area I thought the crash site might be located, used binoculars to look around. Spot something in the trees over a hundred yards away.

  • Zoomed in on what turned out to be a piece of wreckage from the HRS-2. It's color made it hard to see from a distance, the straight line caused by it's shadow is what caught my eye.

  • Just after taking the previous photo, I looked up to see a few deer running up the slope.

  • The other side gives a better view of the damage. It was interesting to see how the blade was constructed. The tailing edge is made up from many individual sections that were glued to the leading edge.
