This reminded me of the two Virginia State Police troopers that were lost in a 2017 VRS crash. There was speculation one of the pilots purposely entered the VRS envelope to demonstrate the so-called Vuichard recovery technique to the other pilot. He had mentioned the method to another State Police pilot days before the crash.
I hope I'm stating this correctly. As I said in an earlier post, from my rotary wing training years ago, I know just enough about helicopters to show I don't know much. But anyway, Vuichard proponents claim initiating lateral movement and aggressive pedal input to exit VRS is superior to the standard technique of forward cyclic and reduced collective input.
The helicopter was seen traveling at a slow forward speed (insufficient airspeed is a causal factor in VRS entry) in an upright position and then it began spinning as it descended into the ground.
