Yes, I giggle! But it's ok, those pilots have not been fired, but they have been "retrained". I guess Delta sent them back to a Part 61 school, where they went back to being told "This is a runway, it is where we land. That, with the blue lights, is where we taxi, hence the name Taxiway."

Imagine your sitting in your hospital bed and the doctor comes in and says, "While doing your surgery, I decided to try a shortcut. You could have died, but you didn't. Anyway, there were a bunch of people observing and they saw what I did. They told the head surgeon and he was mad, so he is sending me to re-training this weekend. I should be back doing surgery by Monday."

Would you come back to him for your next surgery?
Would you want to fly in the back of a plane that these guys were flying?
