The fact that they got away with this is irrelevant as the outcome could have been catastrophic.
In the abstract, of course. But then, walking out your front door "could" lead to a catastrophe. Landing at the
correct airport
has led to many catastrophes - no "could" about it.
What odds are you assigning? 1 in 10? 1 in 35? 1 in 100?
Here's a list of "wrong-airport" landings dating back to 1950. 92 in total.

One (1) resulted in a confirmed fatality (B29 bomber at Ogden UT).
One (1) might (tongue in cheek
) be counted as a "National Security catastrophe" (U.S. military officers mistakenly delivered to an airport in the USSR, instead of in Turkey).
I don't disagree with your post overall - but the "hyperventilation" in that last sentence spoils the effect.
