The Briefing Bell went before dawn but no target came through and there was no flying.—Colonel H.J. MARTIN, O.C. No. 3 (S.A.) Wing lunched with the Squadron and thereafter talked to pilots and observers regarding a signal received from the A.O.C. who appears to be extremely displeased with our formation flying and evasive tactics in ack-ack.We now have 40 complete crews fully trained for day ops.
