Genuine question - is this likely to be a career ender for these guys?
Or a `don't ever do that again' kind of discussion.
The crew will most likely be debriefed, then sent to the sim where they (under intense pressure to save their jobs) will be given a horrific competency check ride designed for them to fail. Once fired, the company will go to the FAA and declare the "problem" corrected.
The sad part is - these fired pilots would be otherwise
the last pilots in the world to ever land at a wrong airport again!
