More details emerge in tragic Air Canada plane crash at LaGuardia airport

We’re learning more about the tragic fatal crash that happened at New York’s LaGuardia airport Sunday, when an Air Canada passenger jet collided with a fire truck. The U.S. National Transportation Safety Board says a runway warning system didn’t set off an alarm before the crash, because the emergency vehicle was without a specific piece of equipment. Both pilots killed in Sunday night’s collision have now been identified.
