The author does a disservice by stating that 7 of 22 attempts at reproducing the problem situation drew long faces on the marines or people overlooking the test.. in all cases the maneuvers were done outside of the prescribed limits, i.e. pilot error!
I also dont agree with the military analysis that in the heat of battle you can't expect the pilot not to push the envelope. If you are on a motorcycle with a lot of power available you can't just wind on as much power as you like to get away from someone chasing you, but have to ride within the prescribed limits of available grip. Similarly the osprey should be flown with full awareness and within its limits.
