"The notion that mandatory spin training was rescinded in 1949 because "we
were killing more pilots during spin training than the training was
saving" is a myth. In the many research papers I’ve read on the subject
from every decade of powered flight, I have yet to come across evidence
substantiating this claim." Quoted from:
