Oi Partz, where does a tangent start????
Your ( and previously my) ground resonance experiences chasing jets at 4pm on a Friday (or any afternoon for that matter) are not the sole preserve of the Lancashire aerospace industry you might be please to know. It appears to be a universal malaise of the shop floor fitter which has realised that if "I can get paid time and a half or double time for working on this jet out of normal hours then why don't I ponce around until management insist on overtime!!"
Ask William the Canadian probe jouster when you see him at SETP....
Having a Guy Fawkes party this year? Hope to be there if you are.
