Look at the super-precise strike on the E-3 sentry that we have pictures of. We know at least one other was hit.

If Iran can do this with AWACS, they can do even more with the hundreds of fighter jets in Israeli and US bases (it's much easier to cover up the destruction of an F-15 or F-35). Once this war ends, I think we'll see that most of the aircraft kills are going to be on the ground.
