@geoffarnold8483 XP-86 first flight was 13 days (9 working days) before Yeager broke the sound barrier in the X-1. In order for this claim to be true, the XP-86 would have had to go through safety of flight validation, various sub systems safety, landing gear retraction and extension, service ceiling, climb rate, handling and performance, engine shut-down/dead stick recoveries, departure characteristics, then straight into high altitude dives down into thicker air trying to break the barrier with the wrong airfoil shape and leading edges.
In reality, the F-86 speed record of 583kts wasn't set until Sep 1948, well short of the speed of sound.
