I have a serious question. Is there a measurable difference in gravity between when you're "facing forwards" in the trajectory around the sun as opposed to when you're "facing backwards"? I.e. when you're parallel to the velocity vector of the earth as opposed to when you're anti parallel.
If the Earth rotates the Sun at thousands of miles per hour, then why can I jump without dying...

That's kinda more of a fluid dynamics question. I'm not even mad. That's unintuitive.

vid tangentially related.

that was pretty awesome

in short: relativity
in long: fuck you

Speaking up late. If you can push yourself towards the floor, either by pushing yourself to the floor by using the railing or something else, then you will momentarily be able to jump. This assumes complete free fall of the elevator. But in complete free fall you and the elevator are falling at the same speed, and to you it will look like you are just floating in the elevator. If you can get to the floor you will be able to jump, but not as effectively as you can on normal ground. If you do successfully jump, then you would hit the elevator ceiling but not very hard, or not if it has no ceiling. However since you wanted to wait until just before impact you won't have time to drift that far. Instead what would happen, is just before impact you jump, then a split second later the elevator crashes to the ground, then another split second and you crash into a crumpled heap of an elevator and likely die. You will only have your body to absorb the impact.
However, there is probably still some friction between the elevator and the shaft, so you will be accelerating down slightly slowly, or maybe significantly slower than complete free fall. This means you will be able to jump very similarly to on normal ground. Instead of "floating" you will seem more like you are on mars gravity or something. So if you jump too soon, you will catch back up to the elevator floor. So you jump at the opportune moment, and still crash into the ground within a second of elevator crashing, and still die.
As another user pointed out, it would probably be safer to lay flat on the ground if you want to survive. This way the deformation of the elevator crashing can more slowly transfer the change in speed to your body, and also brace your spine and neck so they don't bend too much.

Thanks a lot, that's all I needed to know about that matter. Now can you answer the fly stuff? There's more.

like said if you were free falling with the elevator you probably wouldn't be able to "jump"
but for the sake of the question let's say you were somehow standing on it and ready to jump from its floor
both you and the elevator will fall at the same rate, if you somehow manage to push yourself off the floor you would only provide a negligible acceleration upwards which would not be enough to slow you down considerably and you would just hit the ground in an instant after the elevator does
and if you were some sort of super human with incredibly strong legs and had the strength to complete counter your downwards acceleration, you'd just ram yourself into the ceiling
if there was no ceiling, (assuming your the super human) the elevator would just speed up more thanks to you and you'd be safe
