I stand corrected. I went to DAY
site and apparently Ryan International is the same one that operates cargo 727s and the charter passenger A320s and 321s.
Looks like there are quite a few Ryan International flights to Dayton for cargo- so maybe they put all of their planes in DAY
after Emery closed down.
I don't recall Fed Ex having such a presence at IND
before when Emery and Ryan were flying for USPS
