In response to a signal from 206 Group and from 107 M.U. our Engineer Officer proceeded to the latter unit to attend to the fitting of air cleaners to our aircraft. The first fitting was carried out on the aircraft which conveyed our engineer officer, Lt. Sheedy to 107 M.U. and more aircraft of this squadron will be flown across to carry out further fittings so that desert dust storms will no longer be a bugbear as far as the serviceability of our aircraft is concerned.
