The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rules (interactive)
Rule 1- All posts must be legitimate questions. All post titles must include a question.
All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.
Rule 2- Your question subject cannot be illegal or NSFW material.
Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.
Rule 3- Do not seek mental, medical and professional help here.
Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.
Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.
Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding META posts and joke questions.
Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.
On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.
If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.
Rule 7- You can't intentionally annoy, mock, or harass other members.
If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.
Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.
Rule 8- All comments should try to stay relevant to their parent content.
Rule 9- Reposts from other platforms are not allowed.
Let everyone have their own content.
Rule 10- Majority of bots aren't allowed to participate here.

No, they didn't. Enterprise conducted 5 approach and landing tests where she was carried aloft by a 747 and then detached to glide to a landing, three with that aerodynamic tailcone thing, two with mockup main engines to simulate a return from space. Though there were issues with PIO revealed during the last flight, all five of Enterprise's approach and landing test flights resulted in successful landings.
I would not describe any space shuttle as "crashed." Challenger exploded during launch and Colombia broke up during re-entry; destroyed in service yes, crashed no. Enterprise, Atlantis, Discovery and Endeavour all survived service and are on display at museums. No other airworthy space shuttles were built. Explorer/Independence and Inspiration are 1:1 scale models, and Pathfinder was basically a boilerplate meant for testing and incapable of flight.
NASA blew up a LOT of shit before the space shuttle program. Who can forget Ranger 1 aka Stayputnik that blew up on the pad? But I'm especially thinking of a Little Joe launch, which I think was intended to test the Apollo launch escape tower, which developed an uncontrolled roll and threw itself apart. It was actually considered by NASA to be a double success because the escape system functioned correctly when the rocket was legitimately out of control.
Also, the Space Shuttle was THE WORST idea. It was as safe as barb wire contact lenses; it's God's greatest miracle that it only killed 15 people.
Frankly I'm surprised that I couldn't find any disintegrated SLS flight tests with what happened to Colombia. There was something about Orbiter Integrated Tests but I couldn't find some sort of itemized record on it.
I refrained from bringing up ancient stuff like Ranger because that's a much higher R&D milestone to surpass.
The space shuttle never flew unmanned. Enterprise did all her glide tests manned, and STS-1 and STS-2 were flown by 2-man crews.
John Young, commander of STS-1, was informed by fellow astronaut Tony England that the House had included the space shuttle program in the budget on April 21, 1972. At the time, he was standing in the Descartes Highlands on the surface of the Moon in his capacity as Commander of Apollo 16.
