Were you woken up, shaken, stirred or bothered by loud noises in Flagstaff last night at around 9:30? You weren’t the only one. A group of five, F-35 fighter jets from Luke Air Force Base shook some nerves. A spokesman from the base confirmed the pilots of the jets were performing an “ILS or Instrument Landing System practice approach” at the Flagstaff Airport. They added the jets then headed south to complete their mission on the range near the base. Training missions are a common occurrence for Flagstaff. The Flagstaff Airport is a prime spot for military pilots to check off a few things in training. Altitude take-off and landing, night flying and more. There are instances where large cargo planes will fly from the east coast to Flagstaff just for training purposes. The spokesman added the Air Force’s approved flying hours for Flagstaff is from 7 a.m. until 11:30 p.m.
