FINDLAY TOWNSHIP, Pa. -- A United Airlines plane made an emergency landing at Pittsburgh International Airport on Friday afternoon after the pilot reported a hydraulic pressure problem, according to an FAA representative.

Flight 615 from Washington, D.C., to Chicago landed in Pittsburgh without incident and all of the passengers were removed from the plane safely.

A spokesperson for Sen. Roland Burris said the senator and White House aide Desiree Rogers were on the flight.

Burris spokesman Jim O'Connor said Burris reported hearing a bang when they took off from Ronald Reagan Washington National Airport. Then, there were loud noises in the cabin before the plane got "shaky and turbulent."

United spokesman Rahsaan Johnson said there was an issue with one of the multiple hydraulic systems and that "out of an abundance of caution" the pilot opted to divert the plane.

Pittsburgh International Airport spokeswoman JoAnn Jenny said the plane landed on runway 28L and was towed to a gate. The passengers waited for another United plane to take them to Chicago.

No injuries were reported.
