    @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!

      🤯 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.

        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.

          @nexta now do it at 400km/h from a jet, it'd only be like ~30G of acceleration

          @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.

            @anthropy @nexta on rereading, it dump out the back at some speed but not mach2

            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":

              @nexta many years back, ZZ Top did a similar experiment where you’d sit in a spherical steel roll cage and they’d roll you out of the back of a pickup truck on the highway at high speed.

              All was documented in their incredible music: “Master of Sparks”

                @nexta I had to read this several times before I realised what you meant was it was the same speed as the truck was travelling, not the car

                  @pvanheus @nexta IIRC this is a clip from the Japanese TV show ITTE Q, where Nakaoka travels abroad to visit this stunt company to do the stunt (Nakaoka is the one letting go of the spring, not the one in the slingshot).

                    @toddz My uncle flew a lot of exotic stuff -- he's the only person I know with a Mach 2+ pin -- and he told me about the A5. I was quite young so I might be responsible for the inaccuracy.

                        PS: Don't do this near light speed without changing the formula. A few other practical problems might show up too 😉

                        You do not want to be the relativistic baseball.
