HyShot goes supersonic down under

[OldNewYork]

Interesting. This has probably been answered somewhere, but how did Bin Laden know to move? It’s not as if we telephoned to say they were on the way.

Great technology, the development has been going on for quite awhile. The only real gripe I have is how the article begins..with the claim of Clinton going after 0sama in 1998.

The Chinese probably have all these plans already.

speed kills

These hypersonic vehicles are not rockets, as ICBMs are, but work in a fundamentally different way. Rockets carry their own fuel, which includes the oxygen needed for combustion in airless space.

Lost me here. All types of vehicles discussed carry their own fuel (except cannon shells). Rockets carry their own *oxidizer* while these others use oxygen from the air to combust with the fuel they carry, like every other rocket, plane, or missile one would normally imagine.

Nah, just give the X37 the ability to drop off a “brilliant boulder” that can fall from the sky on a specific target. The loiter time for plausible deniability is the key.

[COBOL2Java]

Because they need to be moving quickly to compress air for combustion, scramjets must first be accelerated by piggybacking on a jet plane or rocket.

Oh well, see, the Obama Administration will never approve that research, because, you know, "piggybacking" is, like, not, you know, halal.
