SN - regarding your para 2, if the 'facts' are correct, could it be that the inspector saw the
IN FLIGHT LEAK from his seat and the 'mechanic' missed the
IN FLIGHT LEAK on the
GROUND because the tank concerned was empty?
a qualified mechanic was dispatched to check on the wing immediately after the plane landed
- my italics?
I have to admit that on reading the 'case' as quoted there it looks like a 'fair cop' to me
