John Mohr IS amazing.
The first time I saw him perform was in Galesburg, IL, at the National Stearman fly-in. The runway there has a high crown, with a deep drainage ditch along the far side that he used to HIDE IN on one of his runs.
He dove down -- and didn't come up as expected. From our vantage point, we all thought he had crashed! The crowd stood up and gasped as one, holding our collective breath -- only to see him zoom climb up straight into inverted flight.
Well, "zoom" is relative, of course. The Stearman has a pretty sedate zoom -- which makes the maneuver all the better, IMHO.
Great pilot.
