They mentioned a 2 in. thick sheet of rain falling, which is ~288 cubic in. per 1 foot x 1 foot area, about 10 lbs of water. Falling as a flat sheet at terminal velocity would hit you with a force of 127 newtons. What that means as far as injuries go I have no idea. I’m sure it’d cause a nasty headache at the least though.
Fair warning, I’m terrible at math so I could be completely wrong
I did tweak the drag coefficient while doing the math but I had no idea how to figure out what would be most accurate. The number I got there is with a drag coefficient of 1
A cubic foot of water weighs just under 62 and a half pounds. Atmosphere to slow it down or not, having that land on you from altitude would hurt.

Terminal velocity is only as fast as it is because of air resistance. With no air resistance, the only limiting factor of speed is starting height.
It’s like the experiment with the feather and the hammer they did on the Moon.

Energy would be better to look at than force, since at any distance the force is the same (mass and acceleration aka grsvoty are both static)
