That RiscWorld magazine I mentioned earlier has a separate page advertising the Flight Simulators CD which apparently included, among other things, three FST sims: F-18 Hornet, Mosquito Fire (this one is available from CJ's page I linked earlier) and Spitfire Fury. The HUD/instrument panel in the first two actually looks fairly similar to the ones in MiG-29 Fulcrum and MiG-29M Super Fulcrum.
Speaking of CDs, earlier I found mention of Viper Software's F-16: Operation Black Diamond on the ARI Action und Flight. 2 CD- ROMs für Windows 3.11. ARI DATA CD GmbH was a German software publisher, and they also included the shareware versions of Black Diamond, Berlin 1955 and Private Pilot on two other CDs that are in Hallfiry's collection (ARI 3D Games and ARI Game Pack Windows 95). That publisher also had a BBS/FTP but unfortunately it looks like the flight related downloads section was not archived by the Wayback Machine.
Ron Walker's Skyhawk Attack was featured on the GameHippo freeware game site.
Also I found this flight sim related site via the Wayback Machine which mentions "Jörg's Flight Sim Home Page various military flight sims including the 'Electronic Battlefield' series and Tornado." The page this links to was not preserved. I wonder if this was the same Jörg as the author of Joerg's Flight Sim?
Mic Healey's archives contain a lot of different versions of what appears a Masr-themed game, and an Elite tribute which happens to have a backup of the v1.47 FLY.EXE, but I have not tried it out yet with Jaguar.
BTW, I keep forgetting to ask: Adrian Brown's catalogue mentions several FST sims by Simis themselves, including two versions of Private Pilot. Am I right that these were included with the original FST release and the WWII add-on? (the FST CD contents from Mic Healey's site contains two sims: Private Pilot and Top Gun) Or was something else made available for download too?
