Marine One helicopter crew failed to reach air traffic control before safety incident, report says - Reuters

An NTSB report reveals that the Marine One helicopter crew failed to establish communication with air traffic control prior to a safety incident on August 4. While separate recordings confirm that the crew made warning calls regarding their takeoff preparations, tower recordings indicate that air traffic controllers never heard these transmissions. This communication failure occurred before the mishap, highlighting a critical gap between the pilot's attempts to signal and the controllers' reception of those warnings.
