Allegiant executives were flying plane that ran low on fuel

Well, BINGO FUEL is a military, primarily USAF term unknown to the civilian world unless there is an ex military controller around. It would mean, in it's true sense that he was fixing to dip into his reserve. He made it sound as if he were out of fuel. That said, he may have been if he did not regas after the gate return in Vegas. I don't guess we'll know but pic's show that he unloaded on the runway.

regardless of who messed up or why, we don't ever put an air show routine above the lives of the passengers!

Reckon these bosses just got a small taste of what their pilots deal with daily.

This is obviously a computer problem. Isn't the airline computer (which now does all the flight planning, preflight, walk-around etc, instead of a human having to do it) supposed to check Notams for the destination before it creates and files its plan ? Isn't the ATC computer which receives the plan supposed to check the plan filed by the airline computer to ensure that (among other items) the destination Notams have been verified as noted ?. Isn't the a/c computer supposed to check that adequate fuel is on board for the clearances from the filed plan which the ATC computer read to it ? Aren't the computers supposed to re-do all their plans and calculations whenever there is a delay and revise their plans ? This is obviously a failure of one or more of the computers to review and revise the plans during the delay, take into account the Notams and the now closed landing window, either order more fuel or request a ground hold and to keep the PIC informed.

They really didn't "screw up". There was a misunderstanding on the part of their flight ops as to whether the NOTAM included scheduled pax flights. I can tell you from personal experience that these sorts of things happen all the time. Everybody and their brother on small airports thinks they can close a runway, sometimes with NO notice. That's when you have to exercise your PIC authority and raise some hell.

Going to be hard for a pilot to be declared a screw up when your bosses are these two.

Big difference between management pilots and executives. Every airline has management pilots that also fly the line.
