In the meantime, all Comets were to be grounded until the turbine modifications had been carried out. "The New York Times" reported on 12 January that BOAC had temporarily withdrawn all of their de Havilland Comet jet airliners from service, as a result of the crash, and that the two French airlines that used the Comet—Air France and Union Aero Maritime des Transports—had also suspended their Comet services. BOAC had confirmed that their Comet routes would be flown with alternative aircraft to minimise the disruption to the service schedule. The airline emphasized that the planes had not been officially grounded by the British government, but that the action was being taken as "a measure of prudence to enable a minute and unhurried technical examination of every aircraft in the Comet fleet to be carried out at maintenance headquarters at London airport."
