Both can't be flying, as either you need to flap wings (which no airplane does) or...wings must be stable, (as no bird's are.

One or the other is obviously NOT flying.

Which is it?

Or, are both illusions and myths?

Both fly one flaps it's wings and the other uses an engine of some type.

They both fly.
Airplanes rise when the wings give the plane lift. Air moves faster on top of the wings and slower below it. the slower air pushes on the wings more than the faster air, creating the lift that it needs. The weight on the front and back of the plane is perfectly balanced so that the plane can stay up. There is thrust, or, a force that moves the plane forward. This can be with a propeller or a jet engine. Planes are also built so that there is minimum drag.
When Birds are only gliding, they are flying in the exact same way that an airplane does. When birds are flapping their wings, they are creating the thrust that an airplane gets from its propeller or engine.
And because flying can be defined as traveling through the air or becoming airborne, there could be many different ways to do it, so it could be possible even if birds and airplanes flew in completely different ways.
And since I've held birds just before they've flown, and been on airplanes just as they are flying, I'm almost positive that neither are myths...

You need to do some serious study this site page and it will show you a few things you really should know.

Flying is simply traveling through the air without contact on the ground. There is no stipulation in the definition of flying that specifies that an object is limited to how it can be propelled through the air.

A bird travels through the air with its wings propelling it, while an airplane has a motor to push it through the air.

I hope you are just kidding with this question because it isn't very well thought out.

They are both in flight. and both are implying basically the same technique to achieve loft, or height in the air.

By forcing air underneath the wings, byflaping in birds and jst propulsion in planes.

Plane fly because the top of the wing is curved, so it takes longer for the air above the wing to cross the surface vs the flat bottom of the wing. This creates a difference in pressure resulting in lift. The pressure underneath the wing is higher so it keeps the plane suspended in air. The engines create this flow of air over the wing.

Regardless- they are bpth flying because the definition of flight is not exclusive to one technique of flying,.
Hope this helps!

One definition of flying is "to move through the air using wings". Using that definition, both birds and aeroplanes fly. The definition does not limit the wings to being ridged or flexible,only the utilization of wings to fly.

birds truly fly by flapping their wings .
airplanes are designed to fly , but without flapping their wings like birds.
they fly by raing themselves from the ground and keeping their balance by their wings and their machines.
airplanes are merely raised and made to go high and find their ways to far away places by their machines and the pilots that fly them.
birds fly themselves.airplanes are flown by machines and pilots.
very bright question.
thanks.

Birds fly. Airplane just travel through the air because of the amount of thrust, just as a stone flies if you throw it in the air.

whats a bird and whats a airplane yeah they are deffinatly myths ive never heard of them
but im thinking they both glide thats how they would both fly if they did exist

I suggest a science book.5th or 6th grade should cover birds and planes.Assuming you're not joking.
