Aye the joys.Well sweat is pee in undiluted form.
Our tommys have rather nice covers which are worth there weight in gold and arn't a PITA to get on and off. Ripping the carpets out and replacing with rubber floor matting helps heaps as well. Also if any aircraft is getting run for 5 hours a day it helps.
The wire off was proberly done by the owner to stop the bulbs going quite a common practise in schools its easier than swaping the bulb for a dud one.
To bew honest the schools that have there own maint on site are usually the worst for running snags and horrible barely legal aircraft. With Genghis thread on him getting ramped checked I really hope the CAA is actually going to start going round and not only doing ops inspections but also engineering ramp inspections as well.
