NASA's X-43A Vehicle Ready for Flight

Aielman writes "NASA has set March 27 as the date for testing the X-43A vehicle over a Navy range in the Pacific. It will be testing a non-rocket air breathing scramjet engine at approximately 5,000 mph. This is the second attempt, the first ending in intentional destruction due to course deviations shortly after launch."

I don't mean to sound bitter ...

... but why weren't we doing this 40+ years ago? The X-43 seems to me like a logical evolution of the X-15, which is the kind of thing we should have been working on all this time. Big dumb one-shot boosters to get heavy materials that we never intend to bring back down into space, combined with winged air-launched reusable vehicles for carrying people, instead of hybrids like the Saturn V and the Shuttle ... it seems so obvious, now that we've had decades of a space program which now can't even reliably get people into and out of LEO.

I'd like to think that we will, in the next decade, see a manned descendant of the X-43 which will use scramjets to achieve orbital velocities and rockets for maneuvering in orbit, and will provide human transportation to/from LEO orders of magnitude cheaper than the Shuttle. It's certainly technically possible. But I'm not holding my breath.
