Thanks all and, yes, Whirly & VFE, I'm still enjoying saying 'I'm going to work,' meaning that I'm heading for the airfield!
And it's funny, when I was a civil servant I used to dread the question 'what do you do?' at parties, but now I'm trying to induce it in people!
I have to say that I'm finding the sudden need to deal with commercial pressures at the same time as safety/operational considerations a bit of a learning curve, though.
