LaGuardia flights resume after deadly collision between Air Canada jet, fire truck

Flights have resumed at New York City's LaGuardia Airport after a fatal collision between an Air Canada jet and a fire truck, which was apparently caused by human error. The investigation is focusing on why an air traffic controller allowed the fire engine to cross an active runway and whether staffing practices contributed to the incident. Investigators are interviewing controllers, firefighters, crew, and passengers, while also conducting standard drug, alcohol, and fatigue checks. Early evidence suggests the incident did not involve mechanical failure but rather a breakdown in protocol.
