Federal authorities probing flight that almost ran out of fuel by Laura Lorenzetti @FortuneMagazine July 29, 2015, 3:30 PM EDT E-mail Tweet Facebook Google Plus Linkedin Share icons An Allegiant Air passenger jet was dangerously low on fuel when it forced its way onto a landing strip in Fargo, N.D. that was temporarily closed to most traffic. Officials with the Federal Aviation Administration are investigating why the plane was not properly fueled, reported the Associated Press. The closure had been scheduled due to a practice flight by the Navy Blue Angels. An audio capture of the incident reveals an air traffic controller telling the pilot that his company should have been aware of the closure. The plane, which was flying with 144 passengers from Las Vegas, didn’t have enough fuel to make it to another airport and needed to land at Hector International Airport. Allegiant ALGT said it is cooperating with investigators.
