Let me guess, due to some super strange conspiracy, you cannot link replay where all that happened?
Grab a server replay link: https://warthunder.com/en/tournament/replay/
Go there, find the replay where P-51 went Mach2.
I says it's not possible. Prove me wrong please.
Bugs can happen (like some random rock on map without proper hitbox), but what you describe is just pure fantasy seasoned with frustration and lack of skill.
