It was interesting to take a close look at both a Tutor and a Vigilant as they sat side by side on the static display at the Abingdon airshow yesterday. As an engineer I was horrified at the masses of pin holes in the gel coat on the wing leading edges. Thoughts of the water penetration possibilities and subsequent reduction in the strength of the wings came to mind, no wonder these aircraft have been declared unairworthy. Oh hang on, it was the Tutor I was looking at, no pin holes on the Vigilant.
