    BOSTON (WCVB) — Federal investigators say a runway warning system didn’t trigger an alarm before an Air Canada jet and a firetruck collided at New York’s LaGuardia Airport, killing the pilot and co-pilot.

Logan Airport in Boston uses transponders on runway vehicles and also uses another layer of safety known as runway status lights. Red means “stop” when a runway is active or hot.

“It would signal the tower ‘conflict, conflict,’ former Massport CEO Tom Kinton said. “So they become aware of a potential conflict on the airfield. So if you get an authorization to cross and you still have red lights, you’re going to hold.”

The NTSB said early indications are that the runway status lights at LaGuardia were working.

The agency also said that having two controllers on duty in the control tower is typical for a late-night shift, but has long been a concern.

Investigators are now interviewing them, and the two workers in the fire truck.
