Dozens of F-16 fighter jets are being grounded after technicians were finding cracks near the cockpits.
The Air Force grounded 82 of the jets due to damage found on some of the aircraft. The cracks were reportedly first found in the F-16D model jets, which are the same models used for training.
Luke Air Force Base in the West Valley is directly impacted by the move because it is the largest and only F-16 training base in the world.
The F-16 fleet is set to be replaced by F-35 jets.
