At 18:50 the same day, Lent and his "Staffelkapitän" Werner Hansen took off again from Fornebu in undamaged Bf 110s. During the 40-minute flight, they came across a RAF Short Sunderland flying boat, serial number "L2167", from No. 210 Squadron RAF which they shot down together; Hansen received credit for the "kill". Helmut Lent was awarded the Iron Cross 1st Class () on 13 May 1940 before he was transferred to Trondheim on 18 May. He claimed his second aerial victory of the Norwegian campaign on 27 May over a RAF Gloster Gladiator from No. 263 Squadron RAF, piloted by Flight Lieutenant Caesar Hull.
