In the Netherlands Tesla sold 12.000 model 3 in December. They've sold less than 1000 in Januari (so far). I don't expect sales to pick back up too much. A change in taxes is to blame for this weirdness, and this has happened before with for instance the Mitsubishi Outlander PHEV.
Obligatory link when discussing rocket fuels: Ignition; An Informal History of Liquid Rocket Propellants. By John D. Clark
Very interesting read and a good eye opener on why there are so many superfund sites in the US. (I mean, silly little ideas like adding pure elemental mercury to rocket fuel because nobody wanted to make a hundred pounds of dimethyl mercury for them for some odd reason...)
Slower over the average of the entire flight yes, but aircraft like the F-22 and F-35 can maintain Mach 1+ for extended periods of time (super-cruise). The earlier jets like the Century series could only manage short bursts of Mach 2 and a bit before their engine blew, they ran out of fuel or the airframe overheated (or all three) and flew subsonic most of the mission.
I've now experienced salespeople in shops begging me to give them at least an 8 on the survey that is send out afterwards, or they'll get docked their entire bonus. Which is completely stupid as especially in the Netherlands, NO-ONE is going to give more than a 7 by default, MAYBE an 8 if you've really done an outstanding and superhuman job. It's just not in our culture to be throwing out 10s. How this is even legal in the Netherlands I don't know.
The big problem with solids and not being able to turn them off is that if you stick a capsule with people on top and something does go Kaboom that capsule will likely fall through a cloud of still burning solid rocket propellant chunks and debris, none of which are good for things like parachutes.

Active Noise Cancelling headphones might not be the absolute solution, but for me they absolutely help a lot. Put on some music if you're so inclined and it helps even more! (Or even just some brown or pink noise at low level if you have to focus but want more "blockage". I don't usually use white noise as the higher power density at higher frequencies is a little harsh for long term listening)
A helicopter is merely a collection of parts flying in very close formation in roughly the same direction. It's the pilots job to direct the formation and keep things going the right way. It is the helicopter mechanics job to make keep formation as close as possible.
Correction: "The power of the A10 is not just in directly supporting the enemy. "
Should ofcourse read "in directly supporting ground troops". If your planes are supporting the enemy something has Gone Wrong (tm).
I blame a lack of caffeine today. Coffee maker is on the fritz and percussive maintenance only made sure it was actually dead.
" need to be able to cope with someone standing on them - In boots"
And then some grunt uses it as a stepladder in boots and a full load of combat equipment on his back, and the spec gets amended once again. Next thing you know the next generation of high tech electronic tank traps goes into service. --> We all know where mil-spec will one day lead us.
The biggest problem is that the role of the A-10 makes it inherently an Army (ground forces) weapon, with entirely different operational requirements and principles from the usual mission profiles flown by the air forces. Which means it's difficult for those in charge who grew in the organisation with fast jet experience to understand the complexities of close air support. It is strange the US armed forces seem to have forgotten the lessons learned from the Vietnam conflict, Gulf war and missions in the Balkans.
The power of the A10 is not just in directly supporting the enemy. Guided bombs from high altitude provide only a short " significant emotional event", the roar of a twin turbofan engine coming over a ridge line and the fart of the gods turning your armoured vehicle to dust leaves a much more lasting impression. Knowing that GAU-8 with wings is flying overhead just waiting to BRRRRRRRRRTTTttttt you out of existence provides much more of a deterrent and a morale boost for those on the other side.
So? What is your point?
The astronauts are Americans, the rockets are built at SpaceX in the US of A by American citizens (a requirement to work at SpaceX is that you have a US citizenship afaik) and the launch will happen from the Kennedy Space Center at Cape Canaveral in Florida, which, last I checked and to the grief of many is still part of the USA.
Seems accurate enough. (Go far enough back and the majority of people in the US are immigrants)
He clearly means the "because the beleaguered aviation giant's rockets are very much a single-use affair." bit as not being relevant. SpaceX destroyed a rocket (albeit a used first stage, so less value lost as it had already fattened their bankaccount)
And I agree, it doesn't matter Boeings rocket is single use.
"The investigation conducted by students and interns at the Polytech Orléans and the French research laboratories LPC2E and PRISME by sending a simulation of the Huygens probe through a windtunnel."
Did nobody bother doing aerodynamic stability testing before sending it on it's way? Seems like a basic test to perform and something that SHOULD have been caught.
No, afaik, you can't because sex workers are, well, workers, and are required by law to have a smoke free workplace. (as ridiculous as that sound, a sex worker would have to have a designated smoking spot outside her main "work" area. I doubt there's much inspection for this sort of thing though)
