    @nexta I may be misremembering, but I think Mythbusters wanted to do something like this but it was judged to be too dangerous. This really is very neat!

    @bodhipaksa @nexta IIRC they did it with something like a basketball, not a human. Otherwise pretty much the same though.

      🤯 A visual physics lesson at 80 km/h.

      Enthusiasts launched a man from a moving truck in the opposite direction - at the same speed the car was traveling.

      The experiment spectacularly showed how relative speed works.

      @nexta @davep This video is in the dictionary under “trust” (and “idiocy”)

            @moira @laris @nexta and the video addresses the folks who are chirping in response that it's an unsafe experiment in humans. Lots of test runs building up to it!

                I feel like I'd want to have full motorcycle safety gear just in case the velocity didn't match and you wound up unceremoniously yeeted into a slide

                      @nexta That's why if you run to the back of the plane really really fast you drop out of the sky. 😆 As a kid, the cartoon pink panther had this thing where he would step out of the house just before it hit the ground and I spent like half a day figuring out if that would work or not, only to realize it WOULD work if he jumped up at exactly the speed the house was falling when it hit the ground. Alas such a jump was not feasible.

                        @anthropy @nexta At the height of Cold War madness, we did this with the A-5: it dumped its bomb load out the back on tracks at up to Mach 2, so it would have zero forward speed at release and drop straight down.
                        (It was never used.)

                                      There's also a new podcast with Kari Byron and Tory Belleci called Mythfits and I think they referenced this exact video a few weeks back.

                                        @anthropy @nexta Yeah. There's a limited range of speed where you can use speed in the opposite direction to neutralize the effects on a living creature. Beyond that you're headed into Euthanasia Coaster territory.

                                          Ah - I was just wondering what kind of bomb-launching railgun they had in the fuselage!

                                          I'd never heard of the A-5's unusual bomb bay configuration. Wikipedia explains that the payload "was propelled rearward at about 50 feet per second":
