This has been going on 40 years, there's no reason to think common sense broke out now just because we wanted it to. Hopefully the same people who flooded the FCC site months ago are going to be ready to keep doing this until we can get some concession sufficient enough to weaken the monopolies.

Walmart and McDonalds are most certainly hated for the products they provide. They're just big enough that they don't need to care. They can be viewed as crap by a large chunk of the population and still make money on what's left.

There are plenty of mindless bargain hunters and people with no taste.

In Japan, they found at one point that there was a possibility of it *seriously* going to hell in a hand basket.

If the wind had been really wrong, it would have put serious fallout over Tokyo; which would have been really, really, really bad. While few people would have died, the economic disruption would have been (without any hyperbole) unbelievably stupendous.

You can tell me all you want that this kind of accident can never happen, but I just don't believe it. We have no reason to think that Chernobyl or Fukushima were the worse cases, nor that these kinds of failures cannot happen again worse.

You and siblings missed the gag: capital "F" on fuck was to troll the AC complaining about capitalization, the "American spelling" would be "capitalise," with an "s" in the UK.

In fact all forces should get weaker with distance faster in an expanding space than in flat space.

That seems like quite an assumption on your part, if I'm understanding you correctly. We can't just assume that all properties of spacetime are scaling evenly - if they did, then we'd perceive no effect at all.

But perhaps I'm misunderstanding you.

Some pilots would probably still want the ability to override the limits in an emergency if they feel that they can handle the situation better than the autopilot (for example, if the plane is crashing and the pilot wants better control over where/how to bring it down). If so, then you should make it a possibility to disable the limits, have it such that only *ground* can disable the limits. This would of course impose a delay, but at least overriding the limits would remain a possibility.

Of course, a pilot may try to trick ground into disabling limits (such as pretending to be going down or pretending to have a malfunction), so ground would need as much data as possible to assess whether the situation is legit. Might be tricky... best would be to err on the side of caution and only remove limits if everyone is absolutely sure that this is appropriate, if there's any doubt the answer should be "no".

Not today. But maybe in the future. If you can develop a crazy-power-dense energy source and cooling system, you could probably do it with a MPD thruster. The research I've seen on MPD thrusters operating in pulsed mode yields crazy output relative to the mass of the thruster. But you can't run it continuously because it'd overhead and take way too much power. But who knows about the future? There's the potential for extreme heat conductors like isotopically pure diamond, maybe a some kind of fission fragment reactor with a deceleration grid for power...

(of course, if you have a fission fragment reactor, at least when you're in space itd be best just to jet your fragments rather than use them to power a MPD thruster...)

I hope they simulate propane too, not just methane. Propane has some really interesting properties as rocket fuel but have (like methane) never gotten much research. But now there's a big rush to research methane as fuel based on the concept of generating it on Mars - so propane still gets left in the dark.

Methane's ISP is only very slightly better than propane's - 364,6 vs. 368,3 at a 100:1 expansion into vacuum and 20MPa chamber pressure. But propane at around 100K (note: not at its boiling point, 230K) has far higher density (782 kg/m^3), closer to that of room temperature RP-1 (820 kg/m) then that of boiling point methane (423 kg/m^3), which reduces tankage mass and cost. 100K propane's ISP is of course better than RP-1's 354.6 in the same conditions as above. Plus, its temperature is similar enough to your LOX that they can share a common bulkhead, which reduces mass further and simplifies construction.

Hydrogen generally is the easiest fuel to synthesize offworld. Methane is generally second, and propane third. Hydrogen is often rejected as a martian fuel because of the tankage and cooling requirements. Methane can be kept as liquid on Mars with little cooling in properly designed reflective / insulated containers - but so can 100K propane, in similar conditions, but with significantly smaller tankage requirements.

It seriously warrants more research, I tell you what.

China has their checkbook ready!

... what she did to HP?

No thank you.

I wonder what irrelevant, fourth-rate, POS country that would a complete mismatch and no one in their right mind would ever want anything to do with anyway she has in mind to merge with the USA?

1. Door-locked status: Don't know, but you can't record everything -- there are already plenty of channels that are captured that are far more important

2. Streaming to ground: The NTSB has been working with other air safety bodies to make recommendations to do just that. One issue is available bandwidth: there just isn't enough of it available. So the amount of information that can be transmitted would be limited.

3. Floating black boxes: Like the downlink scenario, breakaway recorders that float are being looked into. More importantly, though, are better crash locator beacons, so the crash debris field can be found more quickly.

In the case of the FDR and CVR, that already happens, sort of. The devices are only able to handle a finite amount of data, and new data overwrites the old. So eventually you effectively get what you are suggesting by normal operation.

And there is a good reason not to dump the recordings. During an investigation of a crash where wake turbulence was suspected to be the main culprit, the investigators had the FDR of the plane ahead of the accident plane pulled to see just exactly where it was in relation to the accident plane. As I recall, the data showed the leading plane was much closer to the accident plane than anyone had suspected, and the wake turbulence would have thrown the accident plane around violently. WIthout the additional data, investigators would not have been able to confirm a hypothesis as to a contributor to the crash.
