19 Décember 1940
Since the previous day, extremely poor weather conditions in Sudan limited air activity. The Vickers Wellesley K7775 of No.47 (RAF) Squadron took off in the night, at 0015 hours, to carry out a supply drop for Mission 101, in support of the Ethiopian patriots in the fight against the Italians. However, the flying conditions were such that Sergeant Keith wis forced to return to Sennar airfield at 04:15, after circling for two hours without finding the rendezvous point.
No.203 (RAF) Squadron continues to conduct maritime patrols with its Bristol Blenheim Mk IVF. Thus, the unit is in charge of a permanent patrol, from dawn to dusk, for the B.N.11 convoy. Three aircraft take part in this patrol. At the same time, an escort of the same type had to be carried out to protect the W.S.4.A. convoy, while at the same time an aircraft had to remain permanently on site to provide anti-submarine protection. In all, nearly 63 hours of flying time are performed by the crews of No.203 (RAF) Squadron during that day.
