I think I'll put the the time period to the mid 1940's 44-47 maybe, as it seems that all the technology we have is semi encompassed in that era.
[/quote]I'm fine with that but then by that time some nations may already have reliable jet engines.
Granted, the lack of grueling competition may mean that nobody is forced to use these and even in real life where WW1 and WW2 happened the jet engines didn't truly replace propeller-driven fighters until mid 1950s or so.
