We had a bad accident here in Minneapolis in front of a large crowd in
the 70s when a replica Curtiss Robin (?) stalled after takeoff, spun in
& crashed killing one and badly burning another.

As I recall the pilot was the local air guard commander who rebuffed
local antiquers efforts to tell him how to fly old airplanes. He had a
lot of multi-turbine time but only a fresh single engine rating. There
was nothing found wrong with the airplane.
