I too have always thought about this. If I was a billionaire, I would also have a secret home setup, and I _would_ take the pilot and his family with me. I would also have a maintenance person and his family there.

I would become his apprentice and have him teach me everything he know. What else would you have to do while you're in hiding?

What makes you think that your mechanic and pilot would teach you anything, or even keep you around in that scenario? What do you have to offer that furthers their survival more than your share of the supplies you're not going to be eating?

If you really want this to work, you better learn to be a pilot and a mechanic now, or preferably have close family members that you like who have those skills.

So you're taking twenty or more people with you? Requiring a larger aircraft which requires more staff which results in more people. Rinse repeat.

Plus the risk of leaks resulting in additional people or those wishing to take your plane.

When you arrive who is feeding, housing, and this large number of people?
