CFI is the only ''ticket'' that requires spins...and not on the checkride...just an endorsement that you have done them with an instructor.
your requirement for parachutes is waived for this.
modern stall training is awful...but remember it is never fully stalled.
and in real life, wolfgang langweische's advice is best...stick forward.
WE will never really know what happened , how this whole thing fell apart.
BUT the fact that both pilots did the wrong thing is an indictment of colgan training and evaluation.
