The end of the pole near the moon would be pulled toward the moon by the moon s gravity and the rest of it would be pulled back. In real life we can t put a metal pole between the earth and the moon 1 for one someone at nasa would probably yell at us. First let s get a few things out of the way.

In most cases there s no atmosphere and the plane falls straight to the ground. Here s what happens when the aircraft is launched above the surface of the 32 largest solar system bodies. The cessna 172 skyhawk probably the most common plane in the world.

Each time it nears the ground it superheats the surface and the plume of expanding air hurls it back into the sky. The box is now soaring through the air. The story eerily foreshadowed the development 30 years later of nuclear weapons.
This means that if you swim near the top of a pool you re going to be just fine and might in fact receive an even lower dose of radiation than if you stood around outside the pool. It turns out that water is an excellent radiation shield which is one reason the spent fuel is put in them in the first place. My recent post history has some good info regarding the spent fuel pool what if on xkcd.
If you have any questions please let me know.
Xkcd nuclear pool. The water temperature in a fuel pool can in theory go as high as 50 c but in practice they re generally between 25 c and 35 c warmer than most pools but cooler than a hot tub. For the kinds of radiation coming off spent nuclear fuel every 7 centimeters of water cuts the amount of radiation in half.
