would you assess this as reckless ?
A resounding yes. You'll note the video says "skills highest level". The man had skill, but when you live on the edge like that it only takes one slip and all the skill in the world can't save you. Ask Dennis Kenyon. Went for a ride, along with other company pilots, when he was demonstrating the 105 in Oz. The most frightening ever, and were glad to get back safe and sound, and the majority of us had seen combat. Was no surprise therefore to read of his demise.
