Federal investigators revealed that temporary landing zone relocation due to White House construction contributed to a close call between Marine One and an American Airlines subsidiary jet near Ronald Reagan Washington National Airport on August 4, 2026, after communication issues prevented the presidential helicopter from issuing required takeoff warnings.
Construction Chaos and the Ellipse Relocation
The physical transformation of the White House grounds has spilled directly into the nation’s heavily congested airspace. Since mid-July, ongoing reconstruction projects—including a controversial new ballroom planned to replace the East Wing and a dedicated landing zone for a supersized Marine One—forced helicopter flights to move from the South Lawn to the nearby Ellipse, a public park just south of the presidential mansion. According to preliminary findings published by the National Transportation Safety Board, that temporary shift in launch location introduced unforeseen radio dead zones that compromised standard takeoff protocols.
Technicians later discovered that moving the helicopter to the park altered its radio line of sight with the airport tower. Federal Aviation Administration technicians determined that the aircraft experienced spotty transmissions because of the altered site geometry, prompting the agency to relocate a receiver to the top of the Reagan National tower to improve communications between the tower and presidential pilots. Aviation safety expert Jeff Guzzetti noted that Even though they were aware of some previous communications issues, they never got at the root cause,
highlighting a systemic oversight before the near-collision.
The August 4 Near-Miss Over Washington
The communication breakdown culminated on the afternoon of August 4, when President Donald Trump boarded Marine One bound for Joint Base Andrews in Maryland.
On that afternoon, however, the Marine One crew attempted at least twice to reach the tower directly but found the airwaves blocked. They also attempted to relay their required notification through a military backup facility at Joint Base Anacostia-Bolling, but that alternate channel also failed. Because the tower never received the warning, air traffic controllers cleared an Embraer E170 jet operated by an Envoy Air subsidiary to depart for Florida.
Marine One lifted off at 2:33 p.m., followed just one minute later by the passenger jet. Preliminary NTSB estimates show that the two aircraft came within 0.82 nautical miles laterally and 700 feet vertically of each other before widening their separation. The passenger jet was promptly rerouted out of caution.
Heightened Scrutiny Following the 2025 Tragedy
The close call immediately drew intense scrutiny because it occurred under strict airspace rules implemented after a January 2025 midair collision near the same airport killed 67 people when an airliner struck an Army Black Hawk helicopter.
While officials emphasized that President Trump was never in physical danger, the simultaneous presence of both aircraft in the active corridor ran contrary to post-tragedy safety procedures.
Officials stressed that the president was never in danger.
Persistent Radio Glitches and Immediate Remediation
The August 4 event was not an isolated glitch. Just weeks prior, air traffic controllers and Marine One staff met on July 30 to address growing concerns over missed three-minute warnings. At the time, flight crews acknowledged that radio links had grown unreliable due to the construction shift and agreed to utilize backup communication channels.
Those operational adjustments proved insufficient when radio contact faltered once more. Air traffic controllers experienced another brief radio loss with the presidential helicopter as President Trump departed for Texas to attend a Republican National Committee event and present an award to the Artemis II astronauts.
“I can’t hear Marine One,” an air traffic controller says to the support helicopter. “If you hear Marine One, can you let me know?”

Communication was restored a little over a minute later with the assistance of a support helicopter, allowing the afternoon flight to proceed without further incident. The FAA reported that it took immediate action following the Aug. 4 incident involving Marine One, including relocating an antenna to improve communications between ground controllers and flight crews, with subsequent checks showing no further communication failures.
Unresolved Infrastructure Concerns
As federal safety investigators continue their formal review, questions remain regarding the long-term design of the presidential helipad itself.
With the NTSB investigation remaining active, federal regulators have yet to release a final determination on whether structural changes to the White House grounds will require permanent modifications to regional air traffic control procedures in one of the nation’s busiest and most congested airspace corridors.
