Had a P-3 cut in front of me on final to THL a back in my regional days. He was doing left closed traffic and was supposed to turn downwind behind us, but turned in front instead. We got an RA and pulled up. The ironic thing was, we had a DAL jumpseater, who was also the Training Director for the reserve unit the P-3 was from. His quote, "Outstanding job handling it boys, don't worry about it, that guy's a** is mine."
