    Gun launches still need an engine and fuel to run it. The orbit that the gun puts you in will necessarily intersect the atmosphere, so you need a circularization burn at the top to stay in space. It is of course much smaller than what you need to get to space using a rocket all the way, but you definitely need it.

    You think that existing rockets don't have vibration problems? Get real!

    Funny you should mention Apollo 13. On launch it came within seconds of total destruction due to a pogo oscillation in the second stage center engine that was vibrating at 68 gees, flexing the thrust frame by 3 inches at 16Hz. By complete, pure luck, a fuel sensor tripped and shut the engine down literally seconds before the entire rocket was destroyed.

    Apollo 13 was also a huge failure of engineering. Remember all that improvisation they had to do to fit the CO2 scrubbers from the one craft into the other? Why were they not interchangeable? And of course the root cause of the famous accident was due to faulty design and faulty engineering procedures. The wires which triggered the explosion were clad in teflon (not exactly the strongest material), and the whole tank had been dropped during an equipment swap for Apollo 10. Tests indicated that there was no damage from the drop, but in fact there was; it was this drop that directly led to the explosion. And lastly, there was no backup of any kind. The fact that the three Apollo 13 astronauts survived at all was a triumph of quick-footed improvisation but overall the flight exposed a lot of problems with the system.

    We love to look at Apollo through rose-colored glasses, but the facts just don't support it. Both the Saturn V and the Apollo spacecraft had many problems. There were only 11 flights, but one was nearly destroyed (Apollo 13), and three astronauts were killed in a separate incident. In contrast the Shuttle has flown over a hundred times. Yes, the Shuttle has many problems too, but it's not as if the Saturn V/Apollo combination was some magical example of engineering perfection.

    3. Basically all space rockets are aerodynamically unstable. This is absolutely nothing new.

    4. Before it was eclipsed by an even worse event, Apollo 13 briefly scared the crap out of everyone involved when the center engine of the second stage nearly ripped the entire rocket to little pieces. It was experiencing pogo oscillation, flexing the massive thrust frame by three inches at 16Hz, experiencing 68 gees. Just before this incredible vibration destroyed the entire craft, a fuel sensor was falsely tripped and shut the engine down, saving the ship.

    Saturn V and Apollo were full of problems. Rocket science is hard, remember? I suggest that you get a clue before you mindlessly criticize.

    You think the Saturn V didn't have many tons of anti-vibration structure, anti-pogo devices, and other such things? Get real!

    Clueless computer types such as yourself might think that a rocket should be fuel tanks and an engine and nothing else, but that's not how it actually works in the real world. There's a reason that "rocket science" is used as an idiom to indicate something that's extremely hard, you know.

    Yeah, extra weight reduces the performance, you're right.

    So let's get rid of the fuel tanks. After all, those things are heavy. And how about the engines? Those things weigh a lot. All that cabling from the flight computer is awfully massive too, and the fuel lines, and the gimbals, and especially all of that terribly heavy safety equipment!

    Plutonium is not very radioactive. Its activity is fairly low. The half life of Plutonium 239 is approximately 24,100 years, meaning that any given atom probably lasts a very long time before decaying. In turn this means that the number of atoms decaying at any given moment is quite small. Furthermore, Plutonium decays in the form of alpha particles, which don't penetrate at all. Alpha particles are stopped by human skin, still in the dead bits, and thus are completely harmless when external to the human body. You can hold a big lump of Plutonium in your hand all day and not have the slightest ill effect. It only becomes dangerous when ingested, and even then it tends not to be absorbed by the body except in certain forms, for example fine particles breathed into the lungs.

    As for toxicity, it's pretty bad, but not nearly as evil as it's made out to be. I'd certainly rather have a little more Plutonium around than live with the many tons of mercury per year emitted straight into the atmosphere by the average coal plant, given the choice between the two.

    Lastly, consider that several tons of Plutonium have been released straight into the atmosphere as a result of nuclear bomb testing, and there hasn't been any real environmental harm from this. It's certainly no good thing, but on the other hand this is vastly worse than what happens with nuclear waste, which is safely stored rather than being vaporized and released into the air.

    You can buy stuff directly with checks, so they are money. Yes, some places don't accept them. Some places don't accept cash either. The important thing is that they are generally accepted. Houses aren't.

    And yes, stocks and investments aren't money. They are objects you own which can be converted into money at the market rate. Ever talk to somebody who plays the market a lot, and hear him say "I made $BIGNUM on the market today!"? Invariably this is said when his stock goes up, but when he has not taken any action.
