I’d pray for rain every jump day.
We had a "commo failure" between the DZSO and a/c. As a SIGDET guy I was mortified one of our radios didn't work until we heard the story. The DZSO took one look at the DZ and decided there was no way in hell we would jump that death trap. Credit for the jump and the AF had to pay for the plane ride? Winner, winner, chicken dinner. No one said a word to our guys about the "broken" radio.
