The F-86 versus MIG-15 saga is an interesting one and large quantities of salt probably have to be taken with regard to both sides claims.
The US, incidentally, had far more than one squadron of Sabers.
It's also worth remembering that the F-86 entered fairly late in the conflict - the main jet previously, the F-80 was outclassed by the MIG's.
The war began largely with prop-driven planes and the US confronted jets only after the N.Koreans were aided by Rusia and China. also one needs to
consider the US losses of planes other than the F-86.
The topic is an old favourite of plane-buffs and there is much to search -quite a nice little discussion board link here:
