It's good to see that despite all the naysayers, NASA still does
incredibly cool things. I watched the X-43A successfully launch on NASA
tv over the Internet, and it turns out that they got Mach 7 out of an
aircraft powered by an air-breathing engine.

Good to see new research like this into aviation. (Not to mention the
success of the Spirit and Opportunity Mars missions).

What happened to the plane after it ditched into the ocean as planned?
Did they try to recover it (successfully?) or did it sink to the bottom?
