If a chunk of Soviet space junk falls on someone's house, does the Russian Federation just shrug and say, "That was the USSR, bruh, sorry." They must have assumed responsibility for the Soviet space program, right? It's sort of like firing a bullet into the air... Doesn't matter how long it takes to come down, it's still your fault if it kills someone.

- WalterBright 4y agoIt seems unlikely that terminal velocity of a bullet would be terribly dangerous.

Falling bullets cause injuries and deaths.” I expect a great difference depending on the size of the bullet.
- eesmith 4y agohttps://en.wikipedia.org/wiki/Celebratory_gunfire https://en.wikipedia.org/wiki/Celebratory_gunfire lists a few deaths. Given the number of people who celebrate with gunfire, it's indeed not terribly dangerous overall. Nevertheless, "it's still your fault if it kills someone."
- WalterBright 4y ago"They found that while bullets traveling on a perfectly vertical trajectory tumble on the way down, creating turbulence that reduces terminal velocity below that which would kill, it was very difficult to fire a bullet in this near-ideal vertical trajectory. In practice, bullets were likely to remain spin-stabilized on a ballistic trajectory and fall at a potentially lethal terminal velocity." So I'm not completely wrong. Of course, if you fire a bullet non-vertically, it's much more likely to have a lethal velocity when it returns.
- eesmith 4y agoMy comment wasn't really one of correct or incorrect. It was meant to highlight russellbeattie's propositional logic ("if it kills someone" then "it's still your fault"). I agree with you that it's "not terribly dangerous"[1]. Your comment seemed to have omitted the premise, so I wanted highlight how it was a non-empty set. [2] [1] It's also not terribly dangerous to drive without a seat belt on either. I don't advise people do so. [2] "Firing a bullet into the air" does not mean it must have time to slow to terminal velocity, nor is a bullet hitting a body the only way to kill. (See "Twenty-three people were electrocuted after celebratory gunfire brought down a power cable".)
- WalterBright 4y agoIf you shoot straight up, it will slow to zero, then fall to terminal velocity.
- eesmith 4y agoLook, I agree with you - celebratory gunfire is pretty safe, and if you want to be safer, shoot straight up. Not only will it slow to zero, but you will be the one most likely to be hurt by it. That said, just because you shoot straight up doesn't mean it will slow to zero. The Wikipedia entry lists "October 12, 2003: Wedding guests in Belgrade, Serbia mistakenly shot down a small aircraft", pointing to http://news.bbc.co.uk/2/hi/europe/3185884.stm http://news.bbc.co.uk/2/hi/europe/3185884.stm . russellbeattie is still right - the person who shot that plane is partially at blame for the damage to the plane and the injuries of the two people onboard. (I say partially because from what I gather, neither person was a trained pilot and were joyriding.)
- toss1 4y agoMythbusters found pretty much the same thing - IF (big IF there) you can fire it EXACTLY vertically so that the returning bullet is just like it was dropped from a balloon or something, the terminal velocity is not lethal However, with any significant angle off-vertical, the bullet still travels in a stable trajectory and orientation, so will impact with a speed much higher than random-orientation terminal velocity, and be potentially lethal, even if passing through some roofing material on the way into your body. So yeah, don't shoot into the air, and don't be around where anyone does...
- Simon_O_Rourke 4y agoThat's surely something mentioned immediately prior to the awarding of a Darwin award.
- retrac 4y agoKosmos 954 crashed in northern Canada with parts of the nuclear reactor still intact. The Soviets did eventually pay part of the bill Canada issued for the clean-up operation. It's the only claim so far made under the Space Liability Convention. [1] And yes, I believe the Russian Federation did inherit liability for orbiting Soviet space junk. https://en.wikipedia.org/wiki/Space_Liability_Convention https://en.wikipedia.org/wiki/Space_Liability_Convention
- Someone 4y agohttps://en.wikipedia.org/wiki/Outer_Space_Treaty https://en.wikipedia.org/wiki/Outer_Space_Treaty says they inherited the USSR’s entry into the “Treaty on Principles Governing the Activities of States in the Exploration and Use of Outer Space, including the Moon and Other Celestial Bodies”, which, among others, states states shall be liable for damage caused by their space objects, so they should fess up. Depending on where it falls, in today’s political climate, they might say it’s part of a special military operation against nazis, though.
