I remember seeing him on the 'The World About Us - Colonel Culpeppers Flying Circus' documentary - he was still flying FIFI (the CAF B-29) aged 65 !!! - and when questioned about his thoughts he was adamant that given the same set of circumstances he would do the same thing again.
And he came across as a professional, humanitarian gentleman.
pretty humbling.
