Two air traffic controllers at LaGuardia Airport left their shifts early on the night of a deadly Air Canada crash, according to sources familiar with an FAA investigation. The controllers are among a dozen that the Federal Aviation Administration has moved to fire as part of a timecard fraud inquiry. The early departures occurred on the night of the incident, which involved an Air Canada plane that crashed during landing.

The FAA's crackdown on timecard fraud has implicated several employees, with these two being the latest. The investigation highlights potential staffing and oversight issues at the airport. The crash itself remains under investigation, but the timing of the controllers' departures has drawn scrutiny.

The FAA has not commented on the specifics, but the move to fire the controllers signals serious consequences. This incident raises questions about air traffic control procedures and accountability.
