Looks preferable to the McGuire rig devised by Project Delta’s Sergeant Major Charles T. McGuire during the Vietnam War. A McGuire rig was simply a 15’ x 3” nylon strap fashioned into a loop large enough for a man to sit in and with a smaller wrist loop sewn into the strap to hopefully prevent the wounded or unconscious from falling out. There are more than a few stories of SOG A Team members hanging on for dear life as the helicopter, in a rush to avoid enemy fire flew away before the Troopers hanging below cleared the tops of the trees.
I recently watched a short documentary on French forces in Africa. One combat (2 x man) helicopter and one reconnaissance (3x man) helicopter.
The 3 man helicopter was shot down; two quite badly injured and the third ok. The combat crew landed and the uninjured crewman carried the colleagues to the helicopter and they held onto the undercarriage to fly out. This was because they could see the Islamist rebels closing in on the site of the crash.
They flew for I believe around 5 minutes to safety and the transfered to another helicopter for final extraction.
Some very brave men!
After watching the vid my thoughts went to Michael Durant and those two brave snipers who gave everything to try and save him I think they both received the MOH posthumously.
The aftermath footage was horrible to see, pity they did not have A10's and let the GAU's sort it out.
I did spie-rigging a few times for training. Weird feeling dangling around. Better have a good bottom guy that knows what he's doing. If he doesn't balance just right the whole string and all on it go spinning...top man vomits, gravity, etc.
