Ryanair Flight FR642 Declares Communication Loss Near London Stansted
On September 22, 2025, Ryanair flight FR642, a Boeing 737-800 registered as 9H-QCJ, experienced a loss of communication while approaching London Stansted Airport. The flight, originating from Valencia, was at 9,000 feet when its crew issued a squawk code 7600, indicating radio failure.
Emergency Response Protocols
The loss of communication instigated emergency procedures to maintain air traffic safety. Controllers responded by securing the surrounding airspace and, if necessary, prepared to deploy intercept aircraft for visual monitoring. Given the flight’s proximity to London Stansted, UK air traffic control and possibly the Royal Air Force were poised to assist until communication was restored.
