I had met a Howard DGA like "Mr. Mulligan" my last year in college. I learned Boeing airliners used Menasco landing gear as did the DC-9 which I was proposing to the USAF as the C-9A so of course when I got good enough at digital models I had to have "Ike" but even with a downloaded "Vega," I got the exhaust ports on the wrong side at first.
