Subdeacon Joe Posted November 23, 2011 Share Posted November 23, 2011 I wonder if it is pure spring water? Security teams, counter-terrorism officers might use explosives. If you're trying to rescue a hostage, that's pretty dangerous because the explosion and the debris can cause damage," said Mr Delf. "Our system uses compressed air and it fires a charge, a big barrel of water - and that impact can smash through a double layer breeze-block wall". In testing, the company used ordinary plastic water-cooler bottles full of water, each weighing 22Kg (48.5lb). "What's great about using water is that the casing shatters and it just sprays out. It means security teams are much closer to the point of entry, giving them vital seconds," Mr Delf added. Now, I may be a bit dense, but that roughly 50 pound weight moving at roughly 900 fps is gonna knock debris on the far side with a good bit of power.

Captain Long Story, US Cavalry Posted November 23, 2011 Share Posted November 23, 2011 Kinetic spalling from something like that would blow out on the inside, not the outboard : where the entry teams where staged.

Charlie Harley, #14153 Posted November 23, 2011 Share Posted November 23, 2011 Interesting idea for sure. The kinetics of a forward-moving 50lb bottle of water would certainly be safer for the rescuers than using an explosive charge that blows in 360 degrees.

Charlie Whiskers Posted November 23, 2011 Share Posted November 23, 2011 After seeing all the blocks blowing in,I'm not sure I'd want to be the one being rescued.Seems like if the hostage was anywhere near all that debris you'd be in worse shape than taking a chance of being shot.

Utah Bob #35998 Posted November 23, 2011 Share Posted November 23, 2011 What is the effect on any hostages? They would be wet and rescued. Or wet and dead. Hard to say. Link to comment Share on other sites More sharing options...
