An example was when AAI used 3 Ryan Airbus for twice-per-day LAX, SFO and LAS service, while we were putting the 737 program in place.
There were 4 A320s which did ATL-MCO turns as well. We also had a nice ATL mech forget to latch an engine cowl which the aircraft promptly shed off the end of the runway in several pieces. There are some nice pics of that one inflight all over the interwebz. Fun times.
