Ignoring your total ignorance of recent history to point out, Joes favorability rating on his state of the Union address was 78%.
78% Bob. 30% higher than Trump’s best poll.
Failure Trump never got 50% approval on anything, and today rates around 30% and falling fast as he supports Putin’s invasion and hates on America, as his obvious attempts to subvert democracy and steal the presidency are exposed in courts, as his total failures as a businessman are exposed through the courts.

This is you pick. This is you guy? I can only hope he’s the 2024 candidate. It won’t be a blue wave, it won’t be a blue tsunami, it will be a blue sea level rise…and likely a red demise.
ROTFLMFAHS! So gratifying watching your anti American hate group lose its power.

Putin didn't invade under Trump. He did however invade with sleep Joe behind the wheel.

Guess Biden is Putin's bitch.
How's Biden favorably rating doing?

Vote While It Counts

newtboy says...

LMFAHS!!!
So delusional and backwards, Bobby. The sky, sea, and land are all orange through your eyes, aren’t they?
4500% increase in voter registration refusals, but no increase in fraudulent applications found. All Republican driven. A vote wrongly denied is the same as a vote wrongly cast, and Republicans are undeniably guilty of both but can’t point to any verifiable examples from the left of in proper vote denial or intentional voter fraud, only cases they make up (like the poster boy for vote fraud claims that finally admitted he voted as his wife for Trump).

It’s all Republican fuckery. Name the Democratic fuckery you mean, be specific with verifiable examples. I know you can’t, snowflake.
Every instance found, all Republican vote fraud. There were many, but not at levels that mattered (for the direct vote fraud, other Republican frauds like the violent coup attempt and fraudulent Republican electors, those mattered).

Every hurdle to vote, Republican written, all directly targeting minorities….it’s only Republicans creating racist targeted roadblocks for certain voters they wouldn’t accept as roadblocks to their own firearm ownership, because it’s not about safeguarding rights it’s only about underhanded power grabs by the political minority in this country, the party who only won one presidential election in the last 8 by getting more votes….they’re Republicans. Democracy isn’t a friend of Republicans.
They’re the party that’s openly anti democratic. They’re the party that admits that if every eligible voter voted they would NEVER win another election. You vote Republican because you’re an infantile sucker that likes to trigger the libtards (no matter the cost to America) and who can’t ever admit he’s w-w-w-w-wrong.

You’re Eric Cartman. Dim, dishonest, and despised.

That's exactly why I will vote Republican. To keep Democrats from their fuckery.

Around Cape Horn (1929)

They went round the wrong way? Jeebus, Chile is a huge leeward shore to avoid... That bit about having to then fight the current to go 200 miles further west before you can turn north so that you have enough sea room not to get smashed onto the rocks of the Chilean coast when the weather turns rough... We had engines at least as a backup, but just in case of emergency. Plus we had weather radar and modern forecasts so we could plan a route to avoid the worst of what was to come. Respect.

I especially loved the part about how sailors on the upper yards like the royals or the masthead being "as close to heaven as a sailor ever gets".

Can Spinlaunch throw rockets into space?

maestro156 says...

Yeah, 20000ft is roughly 6km. The air density is about 1/2 but from what I can determine that doesn't equal 1/2 air resistance, but something more like 90-95% air resistance of sea level.

Having said that, I haven't studied aerospace engineering, so I might be getting the details wrong.

There are definitely some minor advantages to building on a mountainside, but I don't think they outweigh logistical difficulties under normal circumstances.

The idea has a good bit of scifi (and probably scientific) history behind it though. I believe Heinlein used a railgun cargo launcher from the moon in Moon is a Harsh Mistress and a mountainside sled rocket in one of his earlier books.

Project Rho is a great resource for hard scifi and rocketry research for writers. http://www.projectrho.com/public_html/rocket/surfaceorbit.php is the link to a page that discusses maglev, railguns and rocketsleds.

I’m thinking Mt Chimborazo in Ecuador…at over 20000 ft, it’s peak it the farthest from the center of the earth (while not being the highest above sea level thanks to the equatorial bulge).
Sure, it doesn’t remove air resistance or friction, but halving it, even cutting it by 1/3 is a massive leap in efficiency and negates much of the extreme engineering and materials needed to overcome the friction….plus, as you mentioned, there’s the rotational speed advantage from launching on the equator vs Florida.
Also, while extremely minor, there’s also a slight reduction in gravitational pull at those heights. A joule saved is a joule earned!

Using a mountainside might help with structural integrity, but it's not likely to give much air resistance advantage if I'm reading the math correctly. The 5 highest peaks in the US are all in Alaska and and range from just under 5km to just over 6km. Commercial jets using air resistance/density for lift fly at about 10km and even at 38km aerodynamic lift still carries 98% of the weight of the plane (https://en.wikipedia.org/wiki/K%C3%A1rm%C3%A1n_line)

Air density is halved at 5km compared to sea level, but air resistance doesn't diminish as quickly (due to it being multiplied by velocity squared and drag coefficient), and only becomes irrelevant (for short-term purposes) around 100km at the Karman Line.

If we had a 5km peak in Florida, the lack of logistical costs might make the benefits worth it, and if we could build on one of Equador's 5km peaks, then there's the further advantage of equatorial location for optimal rotational advantage (part of the reason we launch from South Florida)

3 rules to live by

noims says...

At my age I also live by 3 rules, told to me at sea at the age of 40.

Never pass a toilet
Never waste an erection
Never trust a fart

It's a good day when you can satisfy two, or even all three rules in a single session.

Undercover: EXPOSING MAGA Hypocrisy on Afghanistan

newtboy says...

The end of the war and resumption of the Third Indochina War would precipitate the Vietnamese boat people and the larger Indochina refugee crisis, which saw millions of refugees leave Indochina (mainly southern Vietnam), an estimated 250,000 of whom perished at sea.
The war exacted an enormous human cost: estimates of the number of Vietnamese soldiers and civilians killed range from 966,000 to 3 million. Some 275,000–310,000 Cambodians, 20,000–62,000 Laotians, and 58,220 U.S. service members also died in the conflict, and a further 1,626 remain missing in action. -wiki

So, millions fleeing as refugees, hundreds of thousands died in their attempts to escape, tens of thousands of allies killed by the VC, far more weapons, vehicles, and equipment left abandoned (and less of it decommissioned) to the enemy and a similar abandonment of the government we had been supporting. The scale of Vietnam was exponentially larger, so were the losses when we retreated. How is Kabul worse than that?

Please explain in detail how Kabul is worse. My guess....you've got nothing.

Kabul isn't like Saigon... it's worse. Biden bots still gonna hump the potato's leg tho.
