Are there any practical uses for a wingsuit, or is it just fun?

I could be misunderstanding, but I’ve heard about sending information by the uncertainty principle (or quantum tunneling?), ie knowing an electron’s speed, & so not knowing it’s location, allowing the electron to ‘jump’ through something it should not be able to - a) do I have the basic principle right?, b) what has been produced by that? Effective testing, I mean

What role, if any, does the underlying quantum nature of the world affect us? Anything we take for granted, but couldn’t exist if quantum mechanics wasn’t real?

I’ve heard a theory that all matter is (or can be expressed as?) an energy waveform (higher & lower energy levels) - do I have that concept correct, & if so how does that interact with qm?

I’ve heard that due to qm, infrared radiation is leaked at the edge of a black hole - if my understanding is correct, what prevents that energy from immediately falling back into the black hole?
