 The station was provided with seven large fuel tanks, which pumped petrol into two large pipes running up either side one of their runways.Once the open flame burners along the length of the main runway were ignited the intense rising heat would lift and disperse the fog leaving a visually clear and illuminated runway.Not all RAF stations were FIDO equipped and when dense fog affected the county it was not unknown for aircraft from several stations to be diverted to RAF Metheringham for a safe landing, returning to their home stations when the foggy weather cleared.
