I just read the procedures handbooks for two different Angel Flight
organizations and noticed that one recommends the call sign "Compassion"
and filing flight plans with the identifier "CMFxxx" and the other,
"Angel Flight" and the identifier "NGFxxx."

I don't know the differences, but I fly for Lifeline Pilots (Peoria,
IL) and they advise us to use CMFxxx.

An interesting thing is that my brain is 'trained' to listen for
Cherokee 62R or N62R, and it tends to tune out ATC calls for
Compassion Flight 62R or Compassion 62. I have missed more than one
call in this manner.
