Rules:
-
Rule 1: posts have the following requirements:
- Post news articles only
- Video links are NOT articles and will be removed.
- Title must match the article headline
- Not United States Internal News
- Recent (Past 30 Days)
- Screenshots/links to other social media sites (Twitter/X/Facebook/Youtube/reddit, etc.) are explicitly forbidden, as are link shorteners.
-
Rule 2: Do not copy the entire article into your post. The key points in 1-2 paragraphs is allowed (even encouraged!), but large segments of articles posted in the body will result in the post being removed. If you have to stop and think "Is this fair use?", it probably isn't. Archive links, especially the ones created on link submission, are absolutely allowed but those that avoid paywalls are not.
-
Rule 3: Opinions articles, or Articles based on misinformation/propaganda may be removed. Sources that have a Low or Very Low factual reporting rating or MBFC Credibility Rating may be removed.
-
Rule 4: Posts or comments that are homophobic, transphobic, racist, sexist, anti-religious, or ableist will be removed. “Ironic” prejudice is just prejudiced.
-
Posts and comments must abide by the lemmy.world terms of service UPDATED AS OF 10/19
-
Rule 5: Keep it civil. It's OK to say the subject of an article is behaving like a (pejorative, pejorative). It's NOT OK to say another USER is (pejorative). Strong language is fine, just not directed at other members. Engage in good-faith and with respect! This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban.
Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.
-
Rule 6: Memes, spam, other low effort posting, reposts, misinformation, advocating violence, off-topic, trolling, offensive, regarding the moderators or meta in content may be removed at any time.
-
Rule 7: We didn't USED to need a rule about how many posts one could make in a day, then someone posted NINETEEN articles in a single day. Not comments, FULL ARTICLES. If you're posting more than say, 10 or so, consider going outside and touching grass. We reserve the right to limit over-posting so a single user does not dominate the front page.
We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.
All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

The CIA is up to something
Could be Mossad, too! Or wind, I guess; Helicopters are death traps
Or their own government, not very well known for stability. Or yeah just a helicopter
Is the government allowed to question the leader's son?
Helicopters are 100% death traps. They are very sensitive to up/down drafts often found in mountain terrain. They have no ability to glide like a plane in the event of an engine failure. If they're not pressurized/o2 equipped they have a maximum altitude which quickly becomes an issue when you are already in the thin air of a mountain.
This is actually not true: https://www.popularmechanics.com/flight/a20559/how-helicopters-land-safely-engine-cuts-out/
My grandfather was a Marine and later a Secret Service agent. He didn't tell many stories, but one of the few he did was about riding a helicopter down to the ground through autorotation during engine-out testing -- this was apparently while they were qualifying the original Marine One for Eisenhower's use.
Helicopters are sometimes rightly derided as "a collection of spare parts flying in loose formation" but in this case it seems like they were spitting in the face of God and daring him to do something about it -- flying into dangerous terrain, in inclement weather, in what very likely was an old and ill-maintained aircraft. That's a lot of bad choices to make at once.
I always heard "10,000 parts and an oil leak trying to get away from eachother".
Or "a helicopter does not fly so much as beat the air into submission".
If it ain't leaking that means it's empty, etc...
Wow, I would have never guessed helicopters could do that. Very interesting read + video!
It is technically true, though. Autorotation only provides some control while going down (and the adds inertia helps, too,) but generally they won’t be getting back to an airport or something the way an airplane could.
The way it works is they pitch the rotor blades to collect head speed on the rotor and then flair just before the crash, using the rotor’s inertia to make one last bit of thrust. They can use some of the energy for control and to get someplace safe, but they’re usually not trying to go cross country.
Done correctly, in a clear area, they can survive. But a clear area is a lot easier to find for a helicopter than it is for
Usually helicopter crashes are fatal, however. Most crashes are caused by pilots though, for example pilots that elect to fly through cloudy mountains….
Totally. We've had our fair share of accidents involving helicopters in my city for instance..
