from the aforementioned news story-
"The FAA says that every flight is required to carry an extra 45 minutes of fuel, which should have been enough to divert the flight to Grand Forks. They tell us "Allegiant's operation center told the FAA the flight had an extra 45 minutes of fuel on board. However, as you know, the pilot said otherwise, and requested landing at Fargo."
Is it a big deal for a pilot to, uhh, be untruthful to ATC?
Looks like someone has some splainin' to do.
