Why not the alien soul crystals that enable flight trying to break free?
- gumby 4y agoI'm glad you brought that up because (no joke) nobody can actually explain how aerodynamic lift works, much less how a plane can fly upside down: https://www.scientificamerican.com/article/no-one-can-explain-why-planes-stay-in-the-air/ https://www.scientificamerican.com/article/no-one-can-explai...

- site-packages1 4y agoI think this just proves that it happens, not why it happens. Also the last flight I took proved that it happens.
- bombcar 4y agoPlanes fly because of climate change. Which causes us to need more climate change as we get more flights. Sad but true.

- maxbond 4y agoMy understanding is that planes don't fly directly upside down, and they angle the wing slightly to make a kinda-sorta-airfoil. How helicopters can turn directly upside down, and fly that way[1], without reversing the direction of their props, that I don't get. (Thinking about it now, I think it turns from a helicopter to a hovercraft? Eg, this is a ground effect?)

- tartoran 4y agoYou mean the soul of the plane? The grand spirit of buoyancy?
