I was surprised how many pilots got into and couldn't recover from a Dutch Roll condition when teaching high altitude stall recovery in the Simulator...and that was with everything working.
And surprised how many never received training on recognition and recovery...
After that I made time to teach Dutch Roll recovery procedures at high, mid, and low altitudes....Then a student complained to the director of training that this training was unnecessary, and I was told to stop teaching it.... That student lost control on all three upsets until taught the proper techniques....He's AA's problem now thank God.
This Air Force Crew paid the ultimate price because someone cut training costs...God Bless To them and their families.
