Living In A Castle
Just like a castle, Campbell installed concrete pillars and a driveway for the aircraft home. There is no way you would think it was the result of a plane crash as it has clearly undergone a large amount of work.
Toss Or Keep
Campbell tried to reuse everything that was already on the plane, though he made sure not to touch the cockpit equipment. The rest of the items on board had undergone modification and restoration to ensure a functional living space.
