Ha, it was Schilling? What is your source? One Spitfire indeed returned to Northolt with some holes - there is a photo of damaged wing in Mushroom's 315 Sqn - but was it the aircraft? Two Spitfires failed to return - plenty of German claims as well. A friendly pilot had a lenghty recognition dog-fight with a Thunderbolt and as he recalled, he got really sweat when found it was an American - he realised he cannot down him but was not sure if American did the same.
