At 15.40 hours, the boat was attacked by the British Catalina aircraft FP183 (190 Sqdn RAF/V, pilot S/L J.A. Holmes) between Iceland and the Faeroes. The aircraft was hit by AA fire during the strafing attack, but dropped six depth charges that fell about 30 metres astern. They then exchanged some gunfire, but U-667 soon dived. The Catalina had been hit in the port engine and the hull and the co-pilot was slightly wounded by a shell splinter. The aircraft made it safely back to Sullom Voe. (Sources: Franks/Zimmerman)

At 15.42 hours, the inbound boat was attacked by the British Liberator aircraft FL977 (59 Sqdn RAF/H, pilot F/L E.E. Allen, RCAF) in the Bay of Biscay. The port wing of the aircraft was hit by AA fire in the first attack run, so they broke off the attack, circled U-667 and exchanged gunfire. The Liberator then dropped a depth charge from 3300 feet to force the boat to dive, but it overshot by 75 yards and did not explode. At 16.33 hours, the next attack was made from low level, but the two depth charges missed ahead. AA fire hit the aircraft ten times and the port waist gunner was badly wounded, so the pilot decided to head for home. (Sources: Franks/Zimmerman)
