 I was a crew chief on fighter jets while in the Air Force. Now when I fly, I listen for a smooth hum from the flight control actuators and landing gear retraction. Smooth, good, clunking sound. Smooth, good. Clunking sound, bad. That's from Jeff in Pontotoc. Mike said it was pretty cool flying inverted. I'm sure you practiced some foreign relations while doing so. Because I was inverted.
