Arthur is still very much with us. Flying open cockpit aircraft always bought new skills and techniques such as pasting a chart to a piece of thin marine plywood. All that to save a blurred flash as your chart gets whipped away by the slipstream during aerobatics.
Some of Arthur’s aero’s would may have been inspired by sheer exuberance, but the majority probably came from just trying to stay alive. Here is the remnants of his effort after a bullet smashed it during combat.
See The Memorial Flight to look at a very fine SE5a restoration.
Perhaps the best WW1 aircraft restoration website on the web.
