A Philadelphia-bound flight from Maine made an emergency landing at Logan Airport this afternoon after a situation with a passenger.


Television news helicopters showed the Air Wisconsin plane rolling toward an area at Logan where passengers walked off the plane.


However, it is still unclear what exactly happened on the plane.


A Logan spokesman told the Globe that an "unruly passenger" forced the plane to land.


However, WHDH reported that the man had a seizure while in flight and there was confusion as to what was occurring.


A spokesman for Logan and a spokeswoman for Air Wisconsin did not immediately return messages.
