Most of the Lancasters' return flights were uneventful, all returning to the UK after completing flights of an average duration of 13 hours. A No. 617 Squadron aircraft made an emergency landing at RAF Sumburgh after running short of fuel; this was one of the Lancasters that had not released its Tallboy. The damaged No. 463 Squadron aircraft successfully landed on one wheel at RAF Waddington. The airmen were aware that "Tirpitz" had not been sunk, and were disappointed with the operation's results. No. 5 Group's commander, Air Commodore Ralph Cochrane, sent them a message stating "Congratulations on your splendid flight and perseverance. Luck won't always favour the Tirpitz. One day you'll get her."
