Marine One Loses Contact Again as NTSB Cites Communication Failures in August Near-Miss

The same day the NTSB released its preliminary report blaming communication failures for an August 4 near-miss between Marine One and a regional jet, controllers briefly lost contact with the presidential helicopter again. The FAA had relocated an antenna and revised procedures after the first incident. The Ellipse departure site, used since May due to White House construction, remains a factor to watch.
