What clothes would flying-people wear?

Everyone else is speculating when there are proper reality check examples. Flight suits that allow for free movement of wings, legs and tail are a thing. Some also contain diapers, so that your bird ...

Parachute equivalent when there is no ground

You could use the same back-up plan that the majority of flights in real life use: nothing. The vast majority of civilian flights in the real world have no parachutes. If a catastrophic disaster ...

Can birds evolve without trees?

Trees were not involved with the evolution of flight in birds. Birds did not evolve flight from gliders but likely from ground running predatory jumpers, birds and maniraptoran dinosaurs are about ...

Would a steam powered plane be able to cross the Atlantic ocean?

You may be missing why flight didn't happen until the early 1900s. Flight happened when engines became energy-dense enough. That's what they were waiting for. If it could've been done with steam, ...

How would one attack or lay siege to a flying castle?

Let's revisit the premise that the sky-castle has a year's worth of water stored on it. As a corollary to this premise, we should assume that the stored water won't become stagnant or otherwise ...

How do I prevent flight in a cyberpunk future?

In a last ditch effort to prevent extinction (possibly one that worked, after all people are still here) a team of scientists released a swarm of nano-machines into the atmosphere. They form a slight (...

How would one attack or lay siege to a flying castle?

From a safe distance, your sappers excavate a tunnel. The tunnel leads to the tether point of the castle's anchor chain. Bring the tether down into the tunnel from below. Winch it along the tunnel....

Would an evolutionary predecessor for winged quadrupeds start with four legs and gain wings? Or start with two legs and wings and gain extra legs?

How about neither? Tetrapods evolved straight from lobe-finned fish; essentially no-limbs to four-limbs. You could have a similar process, except when the fish were developing limbs they ended up with ...

Possible cause of a world without flying animals

The first flying insects appeared (as far as we know) in the Devonian, some 400 million years ago. Before that there were no flying animals. So not only is a world without flying animals possible, our ...

How to prevent the evolution of human flight?

Magic is a dense material. Magic is quite dense. It tends to fall down with gravity, and tends to cling to the earth. As such, if you get too far above the ground, there tends to be little magic left. ...

What atmospheric density would be required to allow a human being to fly without wings?

We call this "swimming" and you'd need an atmospheric density roughly that of water. The pressure needed to get a gas at that density has serious physiological effects, so just compressing the right ...
