Armourer,
You stayed on 1 type for 22 years, if that aircraft had been in 1 location for all that time would you have ever moved?
If you had been VC10 or Herc or Nimrod Aircrew for those 22 years, and happy to remain thus where do you think you would have been posted?
I lived your time and moved like a moving thing but sometimes your training mean your employment options are really limited
