Thank you for the back handed compliment

but if I was instructing I would not make enough to pay even 10% of my ex wife's maintenance costs

I've never worked it out but I think she costs as much as a King Air.
Also I have zero ME time.
I like your comments about oil sampling

I actually think one could make a good sitcom, based around some airfield and a flying school. There would certainly be enough utterly comical characters, plus tons of sexual harrassment of students, to play with. The stereotypes are
so easy to define in this business.

Not sure where to start on yours, so I will pass this time.
