I know a guy who was involved in some of those "experiments" and spent a considerable amount of time and money on them. He still is very adamant that it just proves that there is some other unknown confounding variable that just proves that the experiment was valid and that the designers of the flat earth already expected the experiments. It's really depressing. I used to really respect him when I was younger.
Also, many of those planes are timeshared. Most of the people I know in those places share a plane with several other people or have small kit planes they built.
I have a model of an F-14 I made as a kid, Microsoft flight sim and a 15 year old flight stick. Does that count? Full disclosure, the F-14 is missing a vertical stabilizer now.
My wife's grandparents used to live in a sky park like that. Right before the birth of my second child I was laid off and my wife was doing her student teaching. Suddenly in a rough situation with no income. Her grandparents came to visit for Christmas and their way of commiserating with us was to say, "I know how it is; we just had to sell our second airplane..." No irony, not joking. They honestly felt that losing one of their airplanes was equitable to losing a job with 2 babies in the house. It's ok though, I came out on top. I have a job now and they're both dead.
They used to use thiopental, which is similar to propofol, with similar onset, both as an anesthesic and for lethal injection. Manufacturers stopped producing it because its use was controversial. Now it's not even available for anesthesia. It would suck if the same thing happened to propofol.
