[quoteNorma - did things change when they contractorised the ground crew? ][/quote]
Certainly in the early days they did, before the company realised that they needed a) more people than they thought and b) people with SK experience!
They are better now. For the "big" jobs, they do not bring in all the off shift eng's (overtime you know) but they will provide a roaming "tiger team" if and where it is required.
