Donald Trump Thinks that the F-35 is Invisible to the Naked Eye...

In fairness to, well, Trumptards, if not Trump himself, it's inconclusive as to whether he meant that you can't see them literally or figuratively, referring to their stealth radar profile.

In the second clip he did specify that he had been asking about dog fights that you'd get in the movies.

I saw the clip, I think. And he was responding to the pilot who apparently had phrased it that way, so that's not conclusive either.

I wonder when the last time was that two supersonic jets engaged in an actual "dogfight?"

Actually, supersonic fighter jets rarely engage eachother at supersonic speeds.  Most jets need afterburners to go supersonic, afterburners will go through a fighter’s entire fuel supply in a few minutes, and acts as magnet for any heat seeking missiles for miles around.

Also When fighters do engage eachother, rules of engagement usually do not allow them to shoot missiles at each other from beyond visual range for the fear of friendly fire.  Also the dynamics of real air combat is such that the practical range at which an air-to-air missile can actually hit an maneuvering enemy fight who doesn’t wish to be hit is far, far shorter than the straight line range proudly proclaimed in missile vendor’s Brouchures.   So in actually practice, when supersonic fighters tangle, the fights are almost always subsonic, and devolve quickly into visual range dog fights.

One other dirty secret, many fighters that are allegedly Mach 2 supersonic, can’t ever come close to match 2 while carrying any missiles.  So Mach 2 is only flying unarmed while running away or serving as targets or live bait.

I probably should have phrased that differently.  What I was getting at is that we live in a world where generally only one side in a war has an air force and the  other guys ride around on camels or pick up trucks.

We don't seem to be all that eager to fight anyone with a capable air defense system.  I get that war is not supposed to be fair but if the other guy can't shoot back it is less a "war" than a mob "hit."  Nonetheless, we feel so proud of ourselves when we blow up a mud hut somewhere.
