Lest anyone think that: "well that is a slow, fabric covered biplane so that is what saved them" the fact you are reading these words are proof the same holds for an RV.
I was turning final, was a little low, and lost engine power. In the few frantic seconds attempting a restart I realized there simply was NO PLACE TO LAND, save the trees. I slowed it as much as I dared telling myself out loud to "DON'T STALL, DON'T STALL" and settled in the tops of some pine trees. The trees we maybe 6-10 inch in diameter 30-40 feet tall. They broke and bent and the plane ended up pointed straight down about 8 feet off the ground. I walked away with hardly a scratch.
Hardest thing was getting out of the plane in its final attitude without breaking my neck.
Of course the RV-4 was a mess but its flying again. Not a whole lot of it is origianal but enough to identify its ancestry if you know where to look.
Funny thing I remember thinking just before impact: "This is going to hurt".
Other than a banged knee it really didn't; not that I'd suggest trying it to see.
