I don’t see how TBH.

By late in the war, the Allies had air superiority.

Even WITH a few German jets in the air, the Allies owned the skies.

The big issue was German production and logistics. It was bad.

Sure WWII Germany knew how to build a jet, but they couldn’t build them or deploy them at any relevant scale.

They can no longer produce precision parts or high quality steel needed to build any serious numbers of jets or even quality traditional planes.

The can no longer get high quality fuel. The lack of good fuel means the plabes they do have can’t run as fast/hard. So allied planes are outperforming them.

Put all this together and its easy to see how allied air power took control of the skies late in the war.

So could the allies have gotten jets? Maybe. But so what?

If they’ve already taken control of the skies, getting a wonder plane that gives them more control of the skies doesn’t really change much.
