In another sign that authorities believe the chaos in Ferguson is fully in the past, flight restrictions imposed during the tense confrontations on the city’s streets have been lifted.

The Federal Aviation Administration had banned flights from operating below 3,000 feet over Ferguson beginning on Aug. 12 at the request of the St. Louis County Police Department. Police had reported that their helicopter was shot at several times during the protests and unrest that followed the shooting death of unarmed teenager Michael Brown.

Last week, the ban was extended at the direction of Missouri Gov. Jay Nixon (D) “to provide a safe environment for law enforcement activities,” according to the notice.

This ban, which was in place for 10 days, was originally scheduled to run through Monday. Instead, an FAA spokeswoman confirms that the restrictions were lifted Friday at 1 p.m. (local time).
