a Gulstream G650 engine costs maybe $4,500,000 to overhaul every 10,000 hours. Times 2.

a Cessna 172 sips about 8 gallons per hour.

A G650 guzzles about 500 gallons of fuel per hour

jet fuel is a little cheaper than avgas though

Only big airports with mandatory ground handling are expensive to land at.

Bet the fuel was cheap back then too!

Also, it was before google maps, so they couldn't just google nearest open bakeries. It might as well have been "nearest open bakery they were aware of". Funny how modern tech made the terms "closest open" and "closest known open" virtually the same.

(In practice, almost all bakeries will be small enough they could open, but I think most won’t.)

I know South Australia has even more restrictions about when businesses can open, legal and customary. I imagine Western Australia to be more like South Australia in such ways than like Victoria, but I’ve not been there and don’t really know.

And that’s these days. Back in the mid ’80s, I’m almost surprised there was a single bakery open in the entire country.

But sure, there are also sometimes rich people and/or hyperenthusiasts who buy their own planes at great cost.

There are similarly people who enjoy car racing, horse riding, sailing, train journeys, and give excuses for their itineries but it's really to spend time on their hobby.

The $100 refers to the additional cost of doing something extra over and above.

People here also have garage built no quite aircraft purely for the fun of it and the challenge of the build:
