how do you guys make the boxed text of posted info? We learned how to use the board instead of triple-posting like a rube. And, your answer, please? About ovens and melting?

now let me ask again how did the mylar film not get damaged by the 1000 degree rocket stream as the lander touched down on the moon? Not until you tell me why my oven doesn't melt. I know it was a couple pages back, but it's really quite a simple premise; my gas oven burns natural gas, which has an adiabatic flame temperature of a little over 1900 °C. It is made of mild steel which has a melting point of something around 1400 °C. One of those numbers is smaller than the other; so why does my oven not melt when I leave it on for hours at a time?

It is a speed; "full impulse" is lightspeed, or as close as you can get in normal space, not a thrust rating.
And no, I have no idea how they manage to get multi-gigaton equipment to 167 million mph in two to three seconds, but I understand it to require "subspace" or, in common parlance, magic.

I think the original Battlestar Galactica was the worst for fighter-jets-in-space flight dynamics. Oh my yes. Even bac when I was watching re-runs in the early nineties (sorry, not quite old enough to have caught the original broadcasts) it bugged me that the fighters slowed down, instantly, to "normal" speed as soon as they let up on the "turbo" button.

playdor, a question for you, on combustion temperatures and engine exhausts:
I have a gas oven. It burns 'natural gas' which is basically methane with a couple of additives for smell. Methane has an adiabatic flame temperature of 1950 degrees Celsius. That same gas oven is primarily constructed of steel. Steel is a common structural alloy which you may have heard of. It also has a melting point, depending on exact composition, of between 1100 and 1550 degrees Celsius. I'm sure I don't have to tell you that all of the values in that range are less than 1950 degrees Celsius.
So, my question to you is, how come I can leave my oven on at maximum for hours without it melting? Or even starting to deform significantly (it is very thin steel)? Or is my oven a fake?

The only way a privatised NASA could function in anything close to the same capacity as the current incarnation is if the government of the USA was its only customer and also its sole shareholder. At which point you have to ask why you'd go to all that trouble to do essentially nothing?

Depends if you're going to a planet where there's an atmosphere worth a damn to generate aerodynamic lift/drag with I guess. I understand that the design was originally a test of a proposal for a multiple-take off lander for either renewed lunar missions or a Mars mission. The idea that a system capable of performing under Terrestrial wind and gravity conditions really ought to be robust enough for the tenuous Martian atmosphere has some merit after all.

It's perfectly possible to write lean, efficient code today; you just have to find a corporation willing to drop legacy support and similar compatibility issues. This is probably why Google hardly ever release desktop apps.

It gets really sad when he starts singing the praises of his sockpuppet, No, that's just ordinarily pathetic. It's really sad, and also hilarious, when he starts arguing with them, even when they're ostensibly on the same side.

Any chance of a citation to go with that?
I mean, not that evidence, or lack thereof, has ever or will ever dissuade the HBs; I just want to read what the alleged paper actually says, not random out-of-context clippings with editorial fill-in.

I still think Skylon sounds like something Gerry Anderson dreamed up. It really ought to look like this: Nono, that's the A2, or maybe her successor (we have 'till 2060 after all). As for the whole skynet/cylon thing, Skynet has been flying for years and has hardly taken over any worlds at all. Not for want of trying, mind.

Personally I'd like to see the Skylon fly. Maybe there's a deal that could be worked out here?

I would say the part where the rocks come alive and attack people. Forgot about that bit, which was silly to say the least. Rocks coming to life and attacking people was handled much better in the Doctor Who story "The Stones of Blood" with Tom Baker. Frankly, the idea of aggressive, vacuum-living lithoforms is still slightly more plausible than no-one in all of Florida catching a Saturn V launch (at night, to 'conceal' it).

According to Apollo 18, the reason why we never went back to the moon was <insert fairly standard mystery-monster horror plot here>
In fact it's so standard it's cribbed straight from Alien - the only thing missing is Sigourney Weaver kicking ass. Specifically: Astromanauts? Check Sent somewhere to investigate without proper explanation? Check Find hostile extraterrestrial life? Check Everyone dies except for the hero? Check Government covers the whole thing up afterwards? Check
