[@randycampbell6307]

Salt water isn't that bad folks, in fact NASA successfully tested and proved dunking spacecraft and parts into the water wasn't a big a deal as claimed so often. They don't do it because for the most part "re-use" wasn't a thing so the effort wasn't seen as cost-effective given how most space programs were run. On the other hand EARLY space programs were more heavily aimed at various types of re-use so the concepts actually got tested more even if they were never used. Early Saturn-1 testing was originally aimed at recovering the first stage for post-flight examination and possible re-use with the H1 engines subjected to extensive dunk/soak/re-furbish testing which pinned a price of about 5% of the original engine costs to refurbishment and reuse of an engine even with days of exposure to salt-water, minimum cleaning, (spray down with fresh water) and then stored for two weeks before refurbishment. Similarly the Air Force extensively studied recovery and reuse of the Gemini capsule for the MOL program and found that while some design changes were needed to make the process easier the Gemini could be refurbished and reflown for a vastly lower cost than a new capsule. The reason NASA is allowing SpaceX to reuse the Dragon II capsules is because they now have an example of how much effect and effort will be needed and what the end quality of a refurbished Dragon will be. It should probably be clear the Dragon is more damaged by flight and reentry than by landing in the water and that is where the majority of 'refurbishment' comes from.

[@antoniomaglione4101]

You deserve more than a simple thumb-up! Your videos impress me for the completeness of both the research and the delivery style. As "Space fan" I followed the evolution of escape systems through the years; Willy Schirra got lucky with Gemini 6. The integrators forgot to remove the dust caps from the fuel feed duct, so the engine never started really, only the turbines did. There were all conditions to fire the ejection seats, but he trusted his sensorial perception that the rocket hadn't moved from the pad, so he didn't fire the ejection seats. I later learned there were risks due to the seat motors firing in the pure oxygen atmosphere inside the capsule, possibly causing harm to the astronauts. Nice to learn that you too were a electronic music expert... My most complex build was a full keyboard synth with (then expensive) 88 x ICL8038 waveform generators, a polyphonic dream for the time. Thank you again for the outstanding video...

This historic walkthrough of crew escape systems really exposes the reckless decision not to have any escape plan for the shuttle. I am amazed that anyone would fly that thing voluntarily.

[@PunksloveTrumpys]

Have you seen the new Netflix series about the Challenger disaster? I didn't know this before but apparently the astronauts who flew the Shuttle were strongly opposed to NASA's decision to allow civilians on board. They knew it was dangerous and signed up knowing what risks they were taking, and didn't think it was right to risk the life of a civilian no matter how much good publicity they would get from it.

[@twisterwiper]

Jared Freeland Yes I have seen it. It was very interesting. As one of them said, they still regarded it as a test vehicle. I’m just very happy that the newer rocket designs happening right now, take crew safety more seriously. So much exciting stuff going on in manned space flight again.

Side note, the Artemis LAS attitude control motor is *not* the first solid rocket motor to be thrust-vectored. Not only were the Space Shuttle's Solid Rocket Boosters equipped with thrust vectoring--which was the *only* means of control until they were jettisoned--but all solid-fuel ballistic missiles (including Minuteman, Polaris, Trident, etc.) use thrust vectoring to steer during boost, too.

While true is still not full correct the difference is that the LAS uses valves formte vectoring, the SRB use there nozzle to controllable vector

Another point worth mentioning with Gemini capsules: You'd be launching through a 100% pure oxygen environment using your ejection seat. AKA blasting on a small rocket through a very very combustable atmosphere. Aside from the additonal propulsion boost, quite detrimental to the crew's health.

I'm surprised there was no mention of Soyuz T-10-1. It's so far the only use of a LES tower with a crew onboard. The rocket was on the launchpad when a failure in the rocket caused it to light on fire. The launch escape system was fired, pulling the crew capsule away with about 15 g of acceleration, and a split second later the rocket violently exploded. The LES saved the lives of the crew, who immediately requested cigarettes and vodka when they were greeted by recovery crews.

His flight occurred just days before Gagarin's, but problems with his spacecraft during orbit caused him to crash land in China after he missed his re-entry spot. Ilyushin was so badly injured, that the Soviets did not want to acknowledge his flight, even though they had accomplished something miraculous in human history. I would love it if you could do a video on this topic.

The Launch Escape System on the Apollo was not switched off automatically. The Astronauts switched it from "Auto" to "Manual" a short time before Staging the S-IC during the boost phase. They depict this in the launch sequence in the movie Apollo 13, although they erroneously show the escape tower jettisoning as a result of that switch change (which didn't happen in real life, as the tower was jettisoned moments after skirt-sep some time after S-IC staging) .
