Very good thinking, Eliacim. I think you are right. It was early fall, on the way back from the Great Little Chicken Ranch Picnic and Flyin at Leonard Pages place and I was over northern Missouri. Im guessing the ground temperature was around 68° and I was passing through something like 7,000-9,000 or so when I did this. My indicated airspeed was up to about 135 138 mph or so when it started so my true airspeed was probably over Vne. My recommendation holds. 1. Check your control system for integrity and tightness 2. Dont approach Vne in antique airplanes. and add one more: 3. Take altitude and temp into account when figuring true airspeed Ed
