Just a simple button would need to not rust/wither over the course of the duration.

Once read a book about a generational ship that had society collapse. People started denying there was even an outside. That their entire universe was The Ship.

Then someone starts reading the manuals, starts getting in the "Forbidden Areas" (cockpit), notices that they are close to a habitable planet and presses the big illuminated button that says LAND.

Thanks! I see what you meant.

I would posit you're the one being the dick here. Making fun of post this woman trying something and failing and of me trying to drag something useful out of you.

So far you still haven't shown to know anything more than me.

THANK YOU!

Man, if you don't know what you're talking about, please start with that.

How should she have done it to qualify as "whole way"?

This doesn't help me at all.

As a layman, what do you "do" halfway though? Isn't it all in the jump and the rest is "we'll see where/how we end up"?

If they're willing to pay you for standing there unable to do your job, I don't see the problem.
