Gunshots heard all around HPP lastnight

"the result of people injured and killed." --- urban myth -- see the myth busters episode....

again: Wikipedia: "And the same terminal velocity is reached for a typical 150 grain bullet travelling in the downward vertical direction — when it is returning to earth having been fired upwards, or perhaps just dropped from a tower — according to a 1920 U.S. Army Ordinance study"

OK, fine, if it is an urban myth that people have been injured and killed by such bullets fired into the air then how does one explain my friend Gary's mom being killed by just such a stray bullet?

She was laying in the bed of a camper shell above the cab of their truck at a state park campground in northern California when a rifle bullet passed into the camper shell and killed her. Trees solid all around the campspace but with a spot open to the sky just around the parking spot. Angle of entry (as best the park cops could tell, lining up the hole in the camper with the place she was struck) indicated someone had shot their rifle some distance away such that the bullet arced up above the trees and then came back down below the treetops to strike her. The bullet was moving slow enough after it penetrated the camper shell (thin aluminum over thin particle board or paneling) that when it hit her it did not kill her outright with hemolytic shock; instead, it ripped an artery open and she, terrified, bled to death before their eyes despite desperate efforts to reach a hospital.

Physics and science --at least of the sort I am fairly familiar with-- suggest whenever theory does not match up with actual results from the natural experiment being performed in fact, then probably there is some variation or aspect of the theory which has not been completely understood (or, sometimes, is just outright incorrect). Empirical field results trump armchair theory. Gary's mom was a real nice gal; there was no other rational explanation for what happened to her, so it is going to be difficult for me to accept that bullets shot haphazardly into the air do not present a hazard.

Myself, I will be taking a very dim view of it if anyone is shooting weapons into the night near my place.

Aloha.

Astonishing skill! This archer is a real-life Legolas and then some!

this topic has gotin a little off track.
Heard the shots, about 4 or 5 semiauto near paradise sounded like somewhere above 4th.

How can you tell the difference between semi-automatic and automatic?

Exactly what I meant. SO sorry for your friend's mother. What an awful thing to happen.

"it is almost impossible to fire straight up, and if you've got any angle at all, the bullet will maintain its nose first attitude, and WILL be coming to earth at lethal velocity. They also emphasised that one should NEVER fire a firearm into the air..."


false... not on this planet. please supply proof of your laws physics as relates to the question

here is mine: http://mythbustersresults.com/episode50 2 flukes is all they could document... and then the testing

They do make the point at a shallow angle one could "lob" the round and be effective... in much the way physics is used to "lob" artillery or large caliber weapons for maximum range. You haven't lived until you have seen large artillery "skipping" rounds along the desert floor on its way to a target, I have seen up to three bounces before hitting the target.

I say again a round fired close to vertical... will return to earth at 120 miles per hour or so after expending its energy. Pure simple 6th grade physics.

.... a round fired at 45 degrees or so... could be fatal at great distances. 45 degrees or so by definition not a vertical shot however... As the rounds energy is not spent before beginning its drop. Retaining is spin and energy and dropping before all the energy is expended, hence the lethality up to five miles with the right rifle and and shallow angle, still a conventional and not a vertical shot as we are discussing here.

Im still of the opinion no one can definitely say they were shots or exhaust backfire....... if it wasn't a back fire and there were a dozen shots fired... If the cops weren't all over the 'hood like ugly on an ape .... you do have a problem

This thread has been totally hijacked. Why don't you physics fans start a new thread where the finer points of angular momentum, strike penetrations, and spin trajectories can be argued ad infinitum?

The basic point here is that gunfire, never mind rapid repeating gunfire, is against the law, unsafe, and completely inappropriate in HPP or any other inhabited place. I don't care if some of you are convinced that people being killed by falling bullets is urban legend. We don't want to find out in a real world lab experiment here in HPP. This is frightening stuff, especially to those who were near it. If you hear gunfire, call the cops immediately.

To answer Devany's question, modern automatic weapons fire so rapidly that the sound is often blurred or buzzy. I'm guessing that what was heard in this instance was a rapidly fired semi-automatic, which can fire as quickly as the trigger can be pulled and is dangerous as hell in these circumstances.
