We said that for some reason the coming of jet planes is delayed by some years,and that in 1950 ATL this technology is not yet fully developed (can be some experimental jet plane as Bell XP 59).
Other events are as in OTL,so we have the Korean war,but without jets.
How change the history of Korean war without jet planes,and which planes
would be used?
I mean not only P-51 mustangs or Corsairs or Lavochkins, but also those piston engine planes developed during WW-II but cancelled for the incoming of jets.
