美国国家运输安全委员会（NTSB）周四发布初步报告，披露了8月4日“海军陆战队一号”与一架客机在罗纳德·里根华盛顿国家机场同时起飞的事件 1。报告指出，在事发前一周，空中交通管制人员已与总统直升机飞行员开会讨论通信问题并商定了替代方案，但在事发当天该替代方案同样失效 1。尽管此次事件未危及总统安全，但暴露出空管与军方之间长期存在的通信故障 1。
根据五角大楼与联邦航空管理局（FAA）的长期协议，军方需在总统直升机起飞前3分钟通知空管 1。塔台录音显示，“海军陆战队一号”飞行员当时通报了“还有三分钟起飞”，但空管人员表示该传输信号破碎，无法读取 1。此外，FAA曾在2025年1月29日客机与陆军黑鹰直升机相撞事故后规定，直升机经过冲突航线时需暂停机场所有起降 1。去年空难后的国会听证会还披露，连接五角大楼与里根机场塔台的热线已失灵超过三年，而FAA此前并未察觉 1。
The National Transportation Safety Board released a preliminary report on Thursday regarding an incident on August 4 at Ronald Reagan Washington National Airport, where Marine One and a commercial airliner took off simultaneously 1. Although the event did not endanger the president's safety, it exposed long-standing communication failures between air traffic control and the military 1. A week prior to the dual takeoff, air traffic controllers had met with Marine One pilots to discuss these communication issues and agreed upon an alternative procedure, which ultimately failed on the day of the incident as well 1.
According to a long-standing agreement between the Pentagon and the Federal Aviation Administration, the military is required to notify air traffic control three minutes before the presidential helicopter takes off 1. Tower recordings indicate that the Marine One pilot reported "three minutes to life," but air traffic controllers stated that the transmission was broken and unreadable 1. Additionally, following a crash on January 29, 2025, involving a commercial airliner and an Army Black Hawk helicopter, the FAA implemented a rule to suspend all airport takeoffs and landings when a helicopter passes through conflicting routes 1. Congressional hearings after a crash last year also revealed that the direct hotline connecting the Pentagon and the Reagan National Airport tower had been out of service for over three years without the FAA's prior knowledge 1.
