Black helicopters fly over Phoenix during military training
But police say there’s no cause for concern: the military choppers are part of a two-week U.S. Special Operations training exercise that the Phoenix Police Department had previously announced.
Police closed down roads around Jefferson and Washington streets for safety Thursday night. A black helicopter hovered around the Sandra Day O’Connor U.S. Courthouse while crews exited the aircraft and landed on the roof of a federal building.
Spokesman Sgt. Jonathon Howard says such activities are planned months in advance.
Police say the training has taken place across the Phoenix metro this week and is expected to last through Saturday.
