Astro, I'm curious now.
Can you give any examples of errant ATPs actually facing criminal prosecution in this country?
That would constitute prosecution to the full extent of the law. Certificate action is another matter, but that's an administrative action, not a prosecution.
A pilot who makes a serious error can expect administrative action from the FAA up to loss of license.
My impression is that felony charges are more than rare.
Showing up to take a flight drunk will buy a pilot criminal charges and this has happened rarely, but I'm not sure that happens in the event of an honest error that brings a bad result.
Harrison Ford does need some attention from the FAA and he'll no doubt get it.
He deserves actual criminal prosecution about as much as do a number of other pilots who've rarely or never seen such a thing.
