The Poor People's Campaign was a march on Washington D.C. to gain economic justice for poor people in the United States that began on this day in 1968, just one month after the assassination of one of its key organizers, MLK Jr.

The protest was also organized by Southern Christian Leadership Conference (SCLC) and carried out under the leadership of Ralph Abernathy in the wake of King's assassination.

After presenting an organized set of demands to Congress and executive agencies, participants set up a 3,000-person protest camp on the Washington Mall, where they stayed for six weeks in the spring of 1968.

Among those demands was a proposal for an "economic bill of rights" that included a commitment to full employment, a guaranteed annual income measure, and more low-income housing for poor Americans of all races.

"I think it is necessary for us to realize that we have moved from the era of civil rights to the era of human rights…

When we see that there must be a radical redistribution of economic and political power, then we see that for the last twelve years we have been in a reform movement…

That after Selma and the Voting Rights Bill, we moved into a new era, which must be an era of revolution…"

-MLK Jr., in a 1967 planning meeting

Someone smart explain why you cant have a thin pretty largely spaced and securely attached mesh on the intake of jet engine to prevent bird strikes

[–] [email protected] 5 points 5 days ago

You need a big number of airs to make the engine work. You couldn't get a screen with enough filtering power to keep birds out and not ruin the cost effectiveness of running an engine. The odds of bird strike are low. Planes and birds don't often fly in the same places. It is just cheaper to replace the engines when it happens than to prevent it.

watch the mythbusters episodes about planes hitting birds, shit will break the mesh and then you have bird plus mesh getting ingested

what if you used carbon nanotubes or whatever

[–] [email protected] 4 points 5 days ago

there probably aren't that many nanotubes in the world. i'm not a doctor but i don't think there's really anything in the sweet spot of strong enough to not let the debris through but porous enough to let sufficient air through, and anything strong enough to not break is going to let chunks through that'll be a problem.

maybe the answer is to have like the garbage disposal in a sink and just grind up whatever is coming in into small enough pieces that it doesn't break the important part of the engine.

bird bits still go through? only sliced?

What if we put a big pneumatic hand on a pole in front of the engine controlled by an AI that could slap birds out of the way automatically?
