FliFast ... Did my tour 1989-99. Based in MDT, BWI (the best), BGM, SYR ... I flew those numbers too. Old Man Clark from Penn was superstitious, hence his affliction for registrations that added up to 7, like you said. (CA = Clark Aviation).
767pilot ... I'll be at Brown in March. I took the scenic route ! The last stop being yet another company that is now DBA USAirways ... I feel like I have been stuck on a merry-go round since 1989 !
I can't wait to step off ...
