I know this is a long shot. I’ve been keeping track of all my airline flights over the past 37 years. After over 200 flights, it still bugs me that I have a handful that I do not have the registration of the aircraft.
I’ve already checked the DOT statistics page. All of the following flights took place earlier than the earliest data available on that page
The flights are:
07 Jun 71: Hughes AirWest flight 812 YUM-IPL-LAX DC-9
07 Jun 71: Golden West DHC-6 LAX-ONT
18 Jun 71: Golden West DHC-6 ONT-LAX
18 Jun 71: Hughes AirWest LAX-IPL-YUM (this flight only operated twice week. One of those days was Friday; I believe the other day was Thursday). This was the middle flight of the day out of 3 flights between LAX, IPL, and YUM.
19 Jul 72: Pan American 707 military charter from SUU to HNL (arrived HNL between 2000 and 2200)
09 Feb 78: Southern Airways 174 GPT-MSY
The flights in red I have no illusion of ever getting the registrations because Golden West operated quite a few flights between LAX and ONT. If I could get a listing of all registrations operated on those days then I could probably figure it out by cross-referencing the times with my Hughes AirWest timetables of the period.
Any help would be GREATLY appreciated.
