The air traffic control hotline connecting the Pentagon and Reagan Washington National Airport has been out of service since 2022, raising significant concerns about flight safety. The Federal Aviation Administration (FAA) revealed the hotline had failed for over three years prior to a recent deadly midair collision. Additionally, probes have been opened following incidents involving Army helicopters that forced two flights to abort landings. FAA officials are facing scrutiny as the inoperable hotline poses serious risks to air traffic coordination in the Washington D.C. area.
