Donald Trump isn’t prone to saying he’s sorry for anything, so no one should have expected him to apologize for the ridiculous assertion he made about 18th-century airports during his “Salute to America” speech Thursday night.

His blaming the mistake on a rained-on Teleprompter does require a certain suspension of disbelief. The mistake went viral, with Twitter hounds around the world poking fun at the president.

Why? Because he made some goofball reference to revolutionary soldiers “taking the airports” while they fought for their independence in 1775. You know the rest of it: The first airplane didn’t take flight until Dec. 17, 1903.

Blame it on the rain, Mr. POTUS

He said the gadget from which he was reading his text “went kaput” in the heavy rain that soaked the event. Does that also explain why he referenced “Fort McHendry,” when he should have said “McHenry,” and that that battle to which he was referring occurred during the War of 1812?

OK. I’m not going to belabor this point. Suffice to say, though, that the president of the United States is hardly a student of the very history of this great country. He made a mistake while seeking to extol the nation’s greatness.

If only, though, this individual — Donald Trump — could just say it loudly and clearly: I messed up. My bad.
