Unfortunately I never got the real DC9 just the sim for the DC9 Super 80, later the MD80. The Super80 had a lot of glitches because we got the first bunch with bad microswithes that caused a lot of problems. I guess that is why I favored Boeing, because that wasn't happening. It was new so had lots of problems. We called it a DC9 with an apple computer because it was always screwing up. Wish I had flown the original. I always trusted Boeing, turned down all A300 bids and all 4 Boeing types I flew never let me down. My favorite was the 757. So much performance and no matter what failed you were good to go. It is an airplane that won't hurt you unless you do something really stupid.
