For some rockets and spacecraft the crew escape system was via an ejection seat, sometimes custom built for the task, sometimes adapted from an existing seat designed for a high performance plane. Here's a great NASA paper on the Gemini ejection seat: https://ntrs.nasa.gov/api/citations/19670019706/downloads/19670019706.pdf For a more general overview this website has collected a lot of good information http://www.ejectionsite.com/ Follow me on Twitter for more updates: https://twitter.com/DJSnM I have a discord server where I regularly turn up: https://discord.gg/zStmKbM If you really like what I do you can support me directly through Patreon https://www.patreon.com/scottmanley ... https://www.youtube.com/watch?v=57f2Vl1Gmqg

Second Stage engine fails at ignition, and the engineering camera is also lost suggesting something violent enough to cause damage beyond the combustion chamber. https://www.rocketlabusa.com/missions/completed-missions/ ... https://www.youtube.com/watch?v=07bs3cT6tYY

By sheer coincidence a number of long incubating space projects have launched in July - Unity, New Shepard, Nauka and Starliner's second demo mission expected to round out the month. It's great to see all these fly, but I have one favourite.... One thing that didn't show any sign of slowing down was SpaceX's booster test in Boca Chica, clearly the experience of failures with Starship testing has at least solidified their testing, welding and ground procedures.

It turns out that many rocket fuels are basic chemicals that are used in everyday life, which means you can find them in regular stores. But you shouldn't be under any illusion that these would work or be a good idea for a rocket. A better way to build rockets is to buy pre-made solid rocket motors, and then get certified by experts for bigger and bigger rocket motors https://www.nar.org/ Explosions and Fire going all the way concentrating peroxide. https://www.youtube.com/watch?v=LhEYaovWxl4 Follow me on Twitter for more updates: https://twitter.com/DJSnM I have a discord server where I regularly turn up: https://discord.gg/zStmKbM If you really like what I do you can support me directly through Patreon https://www.patreon.com/scottmanley ... https://www.youtube.com/watch?v=1Na3reZIYsw
