>Apollo rockets used hydrocarbon (~kero.) and liq. oxygen while the second stage used liq. oxygen and liq. hydrogen
LH2+LO2 gives best bang / weight, so you use it for second stage where you have to lift all the fuel before you use it. But if you need a really BFR the cryo-tanks get really-really big, so you use Aga-fuel+LO2 for the first stage.
Think of it as methanol powered Nascar vs Diesel Tonka truck
>(or why the shuttle required solid fuel boosters)
Fuck, I've run the numbers and these insanely complex cryo engines we reused from the Saturn V 2nd stage aren't going to move the Shuttle. We are going to need some serious help(*)

Don't tuck your trousers into your boots and make sure your fly is done up.
When I was a student there, 20 years ago, the new rail system didn't go all the way to LAX because of legal objections by taxi/rental car companies and didn't go to Pasadena because of Nimbys in posher South Pasadena.
Now the subway goes to LAX but to get to downtown you have to change trains twice at stations both named after local riots....
So, UBER does really well there
>Does that mean there was something "wrong" with the old ones?
God changes his(her) mind quite often
When the implementation was in stone tablets it was a real pain to do in-field updates. You had to send a bunch of crusading knights.
With software updates you can just roll out a quick patch to fix that whole "no-bacon+penis-snipping" bug
>Nixon (defined by the icon) thought he was was only setting up an environment where black voters enjoying a puff of grass could be jailed to reduce people Nixon saw as voting against him.
That's not entirely true. He also wanted to attack white anti-establishment hippies and support central American dictators in their war against the communists cartels.
Getting rednecks in poor states to die from Oxycontin because "only hippies and N**** take drugs. I'm neither so what I take aren't drugs" was a bonus saving on welfare.
Hope they remember to amend their "S-1" to include the statement, "we just started an intimidation suit against somebody for claiming that ARM has security flaws, which could open us upto a regulatory bitch slapping. And we are currently praying that Maria Markstedter isn't an Eu citizen"
I hope they will stop all advertising showing cars driving faster than the speed limit in any Eu country and not driving in an unsafe manner. They will also have to restrict access to Lamborghini Countach and Porsche 911 posters to the age appropriate.
"detect, address and mitigate systemic risks, such as disinformation."
Does this apply to bus builders ?
>Boeing have already demonstrated their inability to build an SST, so thats OK.
Interesting conundrum.
We could give the money to CMOT Dibbler Aviation, but since he has no record of failing to build an SST - it's just possible that he will successfully build one.
So we have to give the handout to Boeing because they are the only ones with a proven ability to not produce a passenger plane.
>No, actually it's passengers who are too cheap to allow airports to run security efficiently.
The airports need you to spend 3hours waiting and shopping. It's what airports make all their money on - the aeroplanes are an expensive annoyance.
There have been a few attempts at business-class only UK-USA flights with no luggage, own security line, turn up 15minutes before and walk straight on - but the airports blocked them.
Perhaps the confusion is that the SR71 took off with almost empty fuel load. It's a very heavy aircraft with the low speed aerodynamics of a brick so had a very high take-off speed. In case of an 'oops' you want the minimum fuel load and mass.
That means you then start flying with tanks full of highly flammable fuel vapour (not good). It had a N2 purge system but with limited capacity, so you want to get the tanks full of nice cold JP7 as soon as possible. This is fine since you are probably going to be doing multiple refuelling to get to the picnic spot to take the photos.
Yes everyone knows it was Anglo-French. But the problem from the American point of view was that the French one went to France, the problem from the French point of view was that no Americans wanted to go to France, no French wanted to fly to America and the flagship of French technical prowess was being beaten by Le Rosbif
>.....was that it wasn't an American product.
Worse, it was French.
After all the costs of the refit following the crash in France, Concorde was just getting back on its feet when 9/11 happened
The attacks killed a lot of Concorde's regular customers and disincentivized a bunch of others from air travel.
Then when we decided on Operation Dodgy Dossier, the "Cheese Eating Surrender Monkeys" failed to see the intelligence in having a war with a country that had bugger-all to do with the attacks.
As a result even when BA Concordes returned to service, Air France were operating at 20%-25% capacity Paris-NY
> is it because MS don't have a monopoly?
You don't need to be a monopoly to be guilty of monopolistic behaviour
If Tesla bought the company running Golden Gate bridge and only allowed Teslas to use it, that would be monopolistic behaviour even though Tesla aren't the only car company.
