Spitfire IX , BS407 (AH-Y)
Circus 257. After take-off, contact was lost with 331(N) Squadron owing to haze. Near Gravesend, however, contact was made - then lost again near Canterbury. This Squadron crossed the coast over South Foreland at 6,500 feet. The Squadron arrived over St. Omer at 15,000 feet, circled around and climbed to 26,000 feet through clouds which were at varying layers of 7/10ths. The bombers and their escort were not seen, so the Squadron set course for Calais. Four enemy aircraft were seen flying along coast from North East 5,000 feet below. One section broke away to engage these e/a but was not able to close sufficiently. No flak was experienced and no enemy shipping seen.
