An American Airlines jet 767 made an emergency landing at Tulsa American Airlines Base in Oklahoma, on June 10.
The Boeing 767 was at the airbase for routine service. The pilot took a test flight but immediately declared emergency, returned to the base, and landed safely.
According to airport spokeswoman Alexis Higgins, the decision for emergency landing was made after the pilot reported a flight control problem.
Only four crew and technical staff members were aboard the jet at the time of emergency landing; all of them exited safely.
