Bundy, a lien over airplanes is common enough and not hard to organise with the right legal eagles doing the work. But those old birds are now just so much scrap. Leaving them parked anywhere except the desert will cost more than what coud be realised in a sale. I believe that all the Ozzie registered ones have had their certificates pulled by CASA because of airworthiness issues. So now they can't be moved anywhere except on the back of a truck. Even that will cost because someone has to pull the wings etc. The Perth Airport Fire Dept should have plenty of old carcasses to practise on.
