And since a parallax second (parsec) is a unit of length (and not of time), it must be defined as the distance to the nearest toilet. :-)

Sure I did, I just like it when a random news report makes me remember. I also wasn't aware that there was something atmospheric faster than the X-15, it's been a while since I was totally clued up about this stuff.

One morning I shot an elephant in my pajamas. How he got in my pajamas, I don't know.

Then it's easy... just wait for non windy days... :rolleyes:

Is that the new camouflage painting? Or is it that the quote of women in leading positions has reached the military as well? ;P :laugh: :laugh: :laugh: :laugh: :laugh: :laugh: :laugh:

The theory explained in the book "Limit" is way cooler.

The narrator got it a bit wrong about why it's easier to go faster in space. Sure, gravity, as he claims, would be an obstacle IF one were opposing it, but the real hero (or lack thereof) is that there's no atmosphere to (1) slow the vehicle down, and (2) heat the vehicle up. It would go even slower under water . . .

No, that's a X-15 covered with ablative heat protection, most probably before the flight.

18,000 mph if memory serves me correctly. Puts a bit of wind into perspective eh? :)

Munchies_Matt

air+velocity=wind HOw fast is a rocket going? :)

Munchies_Matt

air doesnt have any resistance until it has velocity relative to the object whereupon it is wind. ;P

CodeWraith

For example, I also never saw this[^] before, if we are already looking at the X-15.

Daniel Pfeffer

Escape velocity at the Earth's surface is about 11.2 km/sec, which is 40,320 km/hr, which is 25,200 mph.

If you have an important point to make, don't try to be subtle or clever. Use a pile driver. Hit the point once. Then come back and hit it again. Then hit it a third time - a tremendous whack. --Winston Churchill

It's wind if it's the *air* that has velocity, not an object moving through it.

I see, this is your deffinition of wind is it? What do you call a windscreen then? :laugh:

If you get your scientific knowledge from badly-named items then it's just as well you don't work at NASA. What kind of food stuff is a peanut? A strawberry? What's your pencil lead made from? What's tin foil made from? What kind of animal is a koala bear? What kind of animal is a horned toad? Where was Chinese checkers invented?

Just goes to show how far ahead of its time the SR-71 was.

Now you're getting your scientific info from Merriam Webster? Not much better.
