OK, I'll tell my story now, Thanks, Rudder
I was out on a search for a missing aircraft, and it was my turn to observe and the other crewman was flying. He took us up a box canyon (a huge and usually fatal error), and when I looked up and realized what was going on, we were running out of altitude, airspeed, and flying room all at the same time.
I took the controls and headed toward the canyon wall on my right then banked hard left, traded what little airspeed I had in a banking pullup to reduce the radius of turn as much as possible. The left canyon wall was a couple of hundred feet away at most. At the apex the plane was effectively stalled, I kicked rudder in the stall recovery and rolled out wings level just above the treetops heading back down canyon. I had spent all the energy I had.
It was very quiet on the flight back, and I never saw that guy again.
