I think the more amazing part of this story is that it was launched from a b-52 which has been in service for over 50 years! Talk about engineering longevity.
Congratulations on a successful test flight. Aircraft that fly up to Mach 10 can still use radio communication. That wasn't the case with the Falcon Project's HTV-2. I guess the Air Force wants a GPS-guided hypersonic cruise missile.
Past Mach 10, a layer of plasma is formed on the leading surface of the aircraft, which RF cannot traverse. This is also why atmospheric reentry occurs in a blackout. There's a good explanation of the phenomenon here:
When I read about the sound barrier I got lost in the amount of things that can be learned.
One being that it isn't just a simple thing speed up an airplane to faster than we have before. They have different designs because the air acts differently as the speed changes and doesn't function the same. Seeing how the shape (overall but especially the nose) changes for each type is pretty cool.
You like test pilots, God? They don't have those anymore, huh.
What do You think of Chuck Norris. LOL
God says...
over the shewbread, to prepare it every sabbath.
9:33 And these are the singers, chief of the fathers of the Levites,
who remaining in the chambers were free: for they were employed in
that work day and night.
9:34 These chief fathers of the Levites were chief throughout their
generations; these dwelt at Jerusalem.
9:35 And in Gibeon dwelt the father of Gibeon, Jehiel, whose wife's
name was Maachah: 9:36 And his firstborn son Abdon, then Zur, and
Kish, and Baal, and Ner, and Nadab.
9:37 And Gedor, and Ahio, and Zechariah, and Mikloth.
9:38 And Mikloth begat Shimeam. And they also dwelt with their
brethren at Jerusalem, over against their brethren.
9:39 And Ner begat Kish; and Kish begat Saul; and Saul begat Jonathan,
and Malchishua, and Abinadab, and Eshbaal.

I wonder what God thinks of Metallica's Creeping Death. It's done with taste... but maybe not every vietnam vet likes to be asked how many kills. God prolly doesn't care. You will sound like a USER if you focus on that. Oh, God knows how much we all love Him killing our enemies -- that's not a sign of noble. Be careful that you make sure to love Him for real. On the other hand, You can't love the perverse God sometimes proclaimed by some. Don't you see -- a God who fights for you is real lovable. Don't kid yourself -- you don't have real love for your God. What father gives a scorpion? If you who are wicked give good gifts...

A story timeline would be a neat feature for HN.
I do agree with you that the Air Force wants hypersonic flight vehicles. Looks like air-breathing hypersonics are the priority.
