Because of bad weather only two Tac/Rs were flown today, both being abortive. F/Off K G Gillmor with F/Lt J W Cowling attempted a Tac/R of the Arnhem area. The weather being poor, F/Off Gillmor told F/Lt Cowling to return. This was acknowledged. Repeated attempts after that to contact F/Lt Cowling were unsuccessful and he was listed as missing.
