A jet was forced to abort its takeoff when another plane crossed onto its runway, the second such incident in just over a week at Logan International Airport.
The American Airlines jet was moving into position for takeoff when an American Eagle regional jet that had just landed crossed the runway, said Federal Aviation Administration spokesman Jim Peters. He did not know how many people were on the planes.
The jet's clearance for takeoff was canceled, and the FAA is investigating whether the pilot of the American Eagle plane or air traffic controllers were at fault.
Peters could not say how close the planes had come to colliding Tuesday, but The Boston Globe quoted an aviation source familiar with the investigation saying they came within 1,000 feet (300 meters) of each other, reports the AP.
