I happen to be one of those physicians, and also work as a surgeon in Level
I trauma center. Additionally I also had an additional six years of graduate
school and research training along with my multi instrument rating. My
flying time is spent between cross countries in a twin or more fun doing
aerobatics.

Regardless, there is no comparison between the rigors of medical training,
especially surgery, and flight training. As a resident, and still today we
often have to stay up an entire night operating or monitoring a patient who
is gravely ill or injured. There are times when we need to make immediate
decisions regarding the need to do something that might save someone's life
or limb.

Some may call this arrogance, but some times this is created from the
necessity of having the confidence to make critical decisions in the face of
crisis situations. Lack of confidence and indecisiveness can lead to fatal
delays.

The pressures and stresses of making these decisions is much greater than
seeing the ground rushing up at 200k while flying acro- there is simply no
comparison.

Interestingly, while working as a flight surgeon in a fighter unit, I saw
the same attitudes in the pilots- some people called it arrogance, but most
would agree that it was confidence from having to carry out a difficult and
stressful job.
