I understand the P51 could outhandle the Me 262 and the Thunderbolt could outdive it, (the Me 262 did not have dive breaks.) But, they were three very different planes. The Me 262 was closer to the Me 410, it was designed as a Destroyer while the P 51 was an air superiority fighter and the Thunderbolt, expecially the light weitght M variant capable of 470MPH, was just deadly. The P 51 M and P 47 M could have chased down Arados but not quite the Me 262.
Had the war gone on it would have been interesting to see how the second generation Gloster Meteors. Vampires and the Lockheed P 80s would have faired against the second generation german jets including the Heinkel 162A-2. Also, B 29s over Berlin would have had the German High Command running, would we have dropped the A Bomb on Berlin in August of 45? I don't think so unless the Russians agreed.
