Flights had to be diverted from landing at Dulles International Airport Thursday afternoon after a plane declared an emergency and couldn't move off of a runway.
Colgan Air 3884, which originated in Charlottesville, Va., declared an emergency at about 3 p.m.
The plane landed safely, but could not move off the runway under its own power. The passengers were offloaded on the runway and the plane had to be towed to the gate.
Because the runway was blocked, several incoming flights had to be diverted. A few with low fuel went to Richmond.
Others circled until the plane was cleared. Operations were back to normal as of 3:30 p.m.
