Calling Huey drivers, out there:
For the MRB to make contact with the victim (assuming the victim was standing bolt upright at the time), would mean that the tip path plane would be at around 6 feet.
With it's teetering head, assuming the body of the helo was fully dragged back when it hit the victim, what height would the skids be off the ground??
What is the height of the tip of a blade on a huey when it is stationary (parked up) and the blades are horizontal?
I reckon we're talking inches, maybe a foot off the deck????
