- Federal investigators say a runway warning system didn’t sound an alarm before an Air Canada jet and a fire truck collided at New York’s LaGuardia Airport on Sunday night.
- The head of the National Transportation Safety Board said Tuesday that the system didn’t work as intended because the fire truck did not have a transponder.
- The plane was carrying 72 passengers and four crew members when it slammed into the fire truck while landing, killing two pilots and injuring 40 people, including two inside the fire truck.
- Investigators are reviewing the cockpit voice recorder and what was happening inside the control tower moments before the crash.
- Many questions remain about why the airport fire truck was crossing the runway while the plane was landing and why it didn't stop despite frantic, last-second warnings from the control tower.
