Harry, I´m sure you´r enjoying your stay on this forum like me. I´m a member of 4 or 5 other forums (American, German and Czech) but this one is the best and I´m glad I´m here as well. As usually- my search for one German 4 engine bombers killer got me in touch with Erich and he got me here...
And as for your mistakes you´ve done at the beginning...there´s no better teacher than your own experience. Both bad and good...
