On 29 October 1938 Roberts and Fennessy made the now-famous "night dash" from Bawdsey to meet Air Chief Marshal Sir Hugh Dowding on the opening night of the Munich Crisis. Explaining the problems co-ordinating the information from radar, and the edge this would give the RAF if this problem were addressed, the two convinced Dowding to set up the famous fighter operations room in a cellar at Fighter Command headquarters. All of this was completed in only 36 hours. At the time only five Chain Home stations were operational, a number Roberts considered barely functional, and Fennessy turned his attention to rapidly building new stations to complete the network.
