Enjoyed your reply coming out of ORD. Great airspace. Air Willy sure could do and gave us great ROC. The Short Skyvan, I was not too familiar with, but they operated regularly out of POU in NY. Yes, the great straight tail Blue Canoe Cessna U-3, straight tail. We had them in the 111th Tactical Air Support Group (Air National Guard), NAS Willow Grove, PA. My cousin who was a LTC in regular AF routinely flew theT-34’s in his AF Aero Club. Loved it, and many are still around and of course flying daily.
