Aviation expert Steve Cowell says the planes were flying in a formation that is commonly seen in military exercises.
“That was the echelon formation. In other words, they were all lined up in a row,” Cowell said. “It is not uncommon to have these types of planes in formation, especially at night. Often times, you will see them doing this, especially when they are doing training flights, or standard cross country procedure.”MORE NEWS: Irving Firefighters Battle 2-Alarm House Fire
