Geez.
Landing on the wrong parallel runway on the same airport is a BIG no-no.
Landing at the wrong airport. . .sheesh.
Not paying attention? Yacking instead of navigating, is my guess.
Capt and co-pilot will be lucky to just get a months pay docked and an extra check-ride/re-qual.
Landing at the wrong airport doesn’t mean they can’t fly.
It means they can’t navigate.
Being fired likely is in their future.
OK, I did it back in the late 60’s flying my Tri Pacer. On the way back to OR crossing over Texas, saw three airports in front. Called the first one for airport advisory(non controlled), no answer, so on to the next one, called, and got an adviory from the first one, “wind indicates runway 17”. Thinking that it was the second airport clearance, headed for it. on base noted that a 737 was landing in front of me, hmmmm, Then noted that the runway was 16, but hey, that was close to 17! So landed. Car came out said follow me, Got out of the plane, and the driver said the tower wants you to call. “What tower??? oh oh.” Went into the FBO, which had a class room, and the phone was on a post in the middle of a class - Called tower, explained that my wife gave me the wron frequency - it worked.
