Recall all visitors to the hangars in the last 3 months, especially those who have been out of the flying scene for a while. A cleptomaniac can't sit on an oppertunity for longer than that.
Send the info to Namibia, Botswana and Zim.
My thoughts of the culprits. Obviously previously / involved with flying. Mechanically savvy rebuld/ homebuild type. More than likely white, not neccisarily struggling- these bastards would take from their grandmother rather than from their pocket and bribe screw their way through life in general.
Spoken like an insurer or car salesman. This is why the prospect of Australia, Canada and USA is appealling. They don't spend on 8 foot walls, armed response, hi tech alarms, gorrilla grips, tracker systems, survaillance, private courriers, private security, private schools, no more bicycles. Car guards.I hope we all realise that the economy could not afford for theft to stop - WHAT I hear you say well it's true about 10% of new cars sales are from theft and that goes for lots of products purchased. sad but true if theft was to stop tomorrow our economy would not survive!

Let the car and TV dealers go without selling replacement to the insurers for 6 months? If panelbeaters were'nt such ripp-offs, there would be no need to support backyard repairers who replace car componants from wherever.
Why should society have to adjust and just pay for this? Imagine if we would free up 20 % more of our diposable income?
I'm gatvol, from being cleaned out by trusted staff, car smash & grab, bumping my car in car park to fu$%^ing washing taken off the line. Evertime that happens I get just a little more reluctant to be charitable. For the next 6 months they can all .......!.
Good luck retrieving your stuff.
