Ahh yes, they found a crack on a wing in Hong Kong that was leaking go juice, the crew taking the decision without any engineering backup to fly it back to the UK and then report it, the way the skins were produced it could have run like a zip opening, luckily it didn't.
Well if the Line Sqn Engineers had have been there they could have “stop drilled” it
I take it, Nutloose you did not spend too much time working "in the wing" fixing fuel tank leaks
