  • No, folks, hollow point bullets are NOT outlawed by the Geneva Convention – that’s a common erroneous belief. In fact, the Mk 262 round which is an “open tip” (aka hollow point) bullet is in common use by our troops in Afghanistan right now. But even full metal jacket versions of the 5.56×45 round will tumble and fragment upon hitting a “soft target”. The effect is just as messy as a hollow point round.

  • Well, actually they DO make a “.46″, the S&W .460 Magnum. It’s a bit much for a self defense round, however…

  • The question was raised in the article, “…but we seriously doubt its fast enough to provide lift for someone in a wingsuit.” The answer is yes, the car is plenty fast enough. It is a standard skydiving wingsuit and will fly just fine with about 75 mph horizontal airspeed . Another poster wondered about the landing. The guy is wearing a parachute – he didn’t attempt to land the wingsuit, he landed the parachute. As far as the car panic stopping just before a cliff… Watch the ad again. He is actually driving almost parallel to the cliff when he stops. He has a large margin of error there. They filmed the car pointed at the cliff edge after the fact. Is the ad fake? I don’t know if it is or isn’t. But it is certainly possible that it’s real.

  • Yes, DDR85 has it right with respect to the skydiver’s speed at those high altitudes. However, even at “low” normal jump altitudes of 14,000 and below, there is no single “terminal velocity”. The 125 mph number is in the ball park for belly-to-the-earth configuration, but I can vary my fall rate easily 10 mph either side of that by arching harder or de-arching or even switching jumpsuits. And if I’m head down in a chasing dive I’m going about 175 mph, in a stand with my feet down about 155 mph and in a sit, about 140 mph. Each of those speeds is a “terminal velocity” in that body configuration.
