Oh dear...I seem to have hit a raw nerve.
So you have worked with ex hangar people have you? Spent their entire life in a nice warm hangar eh?
You must agree that it is not only ex hangar that ground a/c, it depends on the individual. There are many long time lineys that who ground a/c because they are low on "self esteem" and "good judgement". I was mearly saying that with a bit of common sense and a bit of knowledge gained from the hangar that defects that seem beyond normal line work can be cleared quite easily on the ramp. (Granted, not in Sweden in Febuary). A spoiler actuator change on a Boeing 737 will seem quite daunting to a chap who is only used to refueling and kicking tyres, but to someone who has done many in a nice warm hangar it is an easy job.
The MEL. Quite often a sloping shoulder for the line engineer who does not realise how easy the snag can be fixed. With a bit of knowledge and application, a lot of mel'ed snags would not be in the book.

Spannerhead has had the balls to to back up?
I will log on again!!
PS: Doctor. Do you suffer from high blood pressure?
