    Insurance is a red herring in the American health care debate - insurance simply is not about what Americans seem to think it should be about.

    Precisely this. Over the last few decades many Americans seem to have to come to believe that insurance is a slot machine - one that pays off every time they pull the lever. For every quarter they spend, and they don't want to spend more than a quarter, they get fifty dollars.

    Just because it could have been very much worse doesn't mean this isn't a huge clusterfuck.

    It sounds a lot like the fire code made sure that everyone made it out of the building alive but now you're upset because the fire department tracked mud on the carpet and soaked all your furniture with their fire hoses.

    No, I'm upset because even though the fire code got everyone out of the houses alive - sparks from my neighbors house burning cause my house to burn down too. On top of that, the fire department was in such a hurry and so careless that they backed into and knocked over my free standing garage, rammed my car (totaling it), and then knocked a hole in the wall of the house on the other side of me.
     

    And now you want us to stop building houses and live in tents, never mind that the house that caught fire was made of wood and the houses being built today are made of brick.

    A house made of brick will burn just as readily as a house made of wood. The interior walls, floors, joists, etc... are still wood. It's still filled with flammable contents. The roof is still tarpaper and shingles. There's still an electrical system to short and a gas system to leak.

    Actually, that's not true. (Gemini used ejection seats and had no escape tower.)
     

    Now all that said, I'm not sure how we'd have stacked something with the size requirements of the shuttle without rebuilding the VAB to make it even taller.

    When the crew/cargo area is beside the stages, a failure in the stages is almost certainly to be fatal or destroy the cargo.

    Wrong. Virtually all parallel staged launched vehicles use solid propellant.

    Wrong. Solids can be shut down in flight. (It was first done back in the 1950's.)

    Irrelevant to my basic point. No matter how you slice it, the Shuttle's failure rate is not significantly different from any other vehicle.

    The problem with your analogy is that Facebook isn't a chic 'in' club for young hipsters. It's Disneyworld and *everyone* is there - Grandpa, Grandma, Mom, Dad, all the aunts and uncles, all the cousins... And they don't give a damn which nightclub the young hipsters are currently flocking to.
     
    And like Disneyworld, every one else is seeking to locate nearby (I.E. the 'share' buttons on damn near every website) in order to take advantage of the millions flocking there. What's dying, in the virtual world as in the real, are all the old and increasingly decrepit attractions and lodgings scattered about that can't take advantage of this.

    Yes, I realize that. I also realize that that large amounts of money are spent to make all launch systems and manned craft that reliable. The Shuttle isn't unique in that respect.
     
    I also realize that of the various manned accidents to date (Russian and US), escape systems would have been useful in only a fairly small percentage of them. Out of two hundred odd manned launches, and twenty odd serious accidents - escape systems were or would have been useful in precisely two... And for the Soviet accident in which it was used, the US wouldn't have used theirs - they have a different system (present on the Shuttle) for use during pad accidents.
     
    So, like the poster to whom I responded, you aren't exactly conversant with the facts either.

    We went down the wrong path with the shuttles. I think their main purpose was a plot to make the Soviets copy them breaking their economy. If we would have kept making Saturn V's ( 10 times the lift capacity of the shuttle ) we would be walking on Mars TODAY.

    In some parallel universe where Shuttle development didn't begin in the early 60's and Saturn V production hadn't been canceled in 1965, sure. But we don't live in that universe. In our universe the Saturn V was canceled because there weren't any payloads for it in the pipeline, and no prospect for any in the foreseeable future. (Mostly because reasonable payloads for it cost in the billions of dollars.)

    but the basic fact is that a stacked vehicle (with the crew at the top) would not have had these failures

    No, a tandem vehicle wouldn't have had those failures - it would have had different failures.
     
    But there's another basic fact you're either ignoring or unaware of, the Shuttle isn't the only vehicle to use parallel staging. In fact, there are many such and many flights of them under our belt - and their failure rate isn't noticeably different from those using only tandem stages. Notably, the Shuttle's reliability rate is around 99% - with a couple of tenths of a percentage point of pretty much every other launch vehicle.
     
    Your conclusion that parallel staging is a bad idea or worse than tandem staging is unsupported by facts.

    The problem is, under the law and in certain circumstances, I'm allowed to change my mind. Your suggestion removes that legally protected right and basically places me at the mercy of the processor. No thank you.

    Non-reversible is good.

    Non reversible is bad. Non reversible means the payee has no rights and no recourse after payment is made if the services or goods paid for are not provided or turn out to be faulty. (Or at a minimum, it means exercising those legally protected rights becomes more difficult.)
     

    Are payment processors supposed to be modes of payment, or net-nannies? If anything, non-reversible would mean fewer problems as people won't buy from anything other than reputable stores.

    Payment processors should be held to the same standards as banks and credit card companies - and that they've operated outside the regulatory envelope to date is a problem, a big one. And even reputable stores have problems and bad days now and again. How they react to that problems and bad days is how they became reputable - and non reversible transactions significantly reduces incentives to behave responsibly.

    I find it amusing how US media is worried about Fukushima nuclear contamination of Japan and surrounding arrea, including US territories or... Europe. They seem to forgot hundreds of nuclear tests made by the US both in Pacific and continental US. I wonder which event released more radioactive material in the atmosphere, a few hundreds nuclear test or the damaged reactors from Fukushima?

    That we used to test in atmosphere is irrelevant, that was fifty years ago and what's done is done. That we used to test underground are equally irrelevant, because except for the first few (as we were figuring out the methodology) considerable measures were taken to prevent atmospheric release and again what's done is done.
