Demarcation
Back in 1985 I was working for a NZ Airline planning to use a fleet of well worn Metroliners from a well known Queensland Airline and part of the deal was a spare parts package so off to Brisbane to pack up this stuff.When all the boxes were ready to take over to the Qantas freight shed nobody would move this stuff as around this time major union problems were going on in Queeensland so with the tug and trailer and all decals covered up I got the job to drive across Brisbane Airport and on arrival at Qantas was asked "who are you" and after giving the name of the Kiwi Airline they accepted the freight. I was told moving this stuff from one Airline to another could have shut down the Airport.
