The alert happened just after takeoff, forcing the plane to turn around and land.

The BWI Marshall Airport Fire and Rescue Department responded to the plane which landed without incident. It was then taxied to a gate.

Passengers say their flight was about a half hour in the hour when over Virginia, the pilot turned around and came back to BWI.

“The captain told us we had to go back, they didn’t tell us why. So we came back here and everyone had to leave the airplane,” said Omar Isssa, of Silver Spring, Md.
