W hen Musk and his allies turned their attention to the FAA last month, they identified a problem: The communications infrastructure used by the agency to manage air-traffic control and aviation safety dates to 2002. It still relies on copper-based wiring and traditional radio. It’s showing its age.

The FAA said that several flight crews inbound to the Reagan National Airport reported onboard alerts when no other aircraft were nearby.

The FAA is investigating reports about recent flights at Reagan National Airport in Washington, D.C., receiving false alarms about midair collisions over the weekend.

The Federal Aviation Administration is investigating why multiple pilots received inaccurate collision warnings while preparing to land at DCA.

Without citing evidence, Musk said the air traffic control communication system managed by L3Harris is “breaking down” and "the situation is extremely dire."
