Verified Victories, p.130 in a good chunky paragraph. The date was 7 March 1945. The story and aircraft details are also in the book, 5 footnotes. This section of this chapters deals with some misconceptions about Erich Hartmann. Hartmann is quoted twice in this paragraph, once he states he never lost a wingman and another time he says he only lost 1 wingman so there is a bit of back-and-forth.
Major Capito was shot down but not killed. Acording to his PERS-1 file, he also served with NJG 3 and JG 101 beforehand transitioning to JG 52 in February 1945.
