they always seem to stay exactly the same distance from the ceiling whether the lift is moving or not

Flys don't move with the lift. If the fly is in the air when the lift starts moving up, the fly must also move up -- or it will end up on the floor. If the fly is perched somewhere on the lift wall, then it will gain momentum with the lift. If the fly releases itself from the wall, it first has no problems because it is traveling at the same momentum as the lift, but it immediately starts to lose the momentum and must again fly in the same direction as the lift.
THE FLY IS NOT HELD IN PLACE BY THE AIR IN THE LIFT.

Simple physics. Relative to the lift, the fly is at the same velocity as the lift and thus appears stationary. (Since the lift is acclerating and overcoming gravity, gravity has no effect here). An example: objects you place inside a car never end up in the front, do they? They appear stationary with respect to the car. The same is true with the fly and the lift.

The raise is going down so there could be laminar air-pass previous the outdoors of the raise in an upward course and the burble component could be basically above the roof of the raise. in view that, even although, the air below the raise could be pressurised, there might additionally be some ingress of turbulent air into the raise-cage. Upon noticing the turbulence the fly might react by asserting to himself, "Blimey, luv-a-duck guvner, what's goin' on 'ere? i might greater beneficial watch it or i'm going to bang me 'ead" (it became a London fly) and for this reason the fly avoids touch with complicated surfaces. have faith me, i comprehend approximately those issues.

The air moves with the lift. The fly moves with the air.
It's the same reason why you can't go 1000mph just by hovering in a helicopter.

why dont you get hit by the ceiling when the lift moves down ? lol

Becasue they are flying in the air, they move relative to the air. If the air moves down, they will also move down. Same way with an airplane, if there is a downdraft, the plane descends quickly with the air.

Fortunately for them, they are held in place by the air within the life.
For example, if your windows are wound up in a car and you drive off with a fly in it, it will stay hovering as if the car's not moving.
If you were to wind down the windows and the fly were near it, it will just go "zip!" and out, with the air that's holding it.

Same way that you can thorw a ball up in the air when travling in a car to you the subject the ball is going up and down. To the observer out side the car the ball is travel in a wave motion.

the same way we do...we don't get closer to the ceiling either. They move with the lift, not against it.

because all of the air in the lift moves up with it, it all moves together, its the same in a car.
