You and I have very different definitions of the word "Stable".

That's the thing. All you'd need to do is "shit a brick" at your apogee. No need for any kind of explosive warhead on a weapons platform that high up (think pennies off the top of a skyscraper) and since you're in between scramjet burns at the thinnest part of the atmosphere, there's no wind resistance to spoil your…

"...will be capable of carrying weapons. Unlike the Blackbird, the SR-72 is an armed platform that will be capable of attacking from the edge of space."

I'm sorry, we're what, now? Guys, I know I've said this before, but as a former AF munitions troop, I know from weapons. I like weapons. Some of my best friends…

I won't let that happen again.

You keep using that word... "Bigotry..."

There are at least two barriers: the (hard) barrier over the spout, and the barrier created by the pressure differential between the hot, vapor-rich air stream and the relatively stable air mass it is moving through. The whistling is a by-product of the pressure differential equalizing.

In other words: HOW ALL SOUND…

Yep.

...The point of this is that, with the discoveries man-kind has made in the past 6 months, we've made more progress towards the singularity than we did in the previous 2.5 years (give or take a CPU-cycle).

One of those "Trust, but Verify" things.

According to Einstein, that's a little thing called "Gravity".

No. You will always have a by-product. Space-time is notoriously difficult to get rid of.

been there, done that, and 5 minutes later it was sunny again.

As I was typing up this comment, I kept thinking "wait a minute... doesn't that perfectly describe Alanis Morissette?"

All art is derivative.

This is about as far back as I could find...
