NASA 'Scramjet'

According to the Palm Springs (Cali) Desert Sun:

• If successful, NASA’s third and last X-43A "scramjet" will fly at 7,000 mph for 10 or 11 seconds high over the Pacific Ocean off California and then, like the two other X-43As, plunge into a watery grave.
• That will be the end of the X-43A project, which has cost more than $230 million and has no immediate follow-on program.

I'm sure that this project has some great implications for the future, but I think $230 million would be a great way to start building a large wall between Mexico and the United States. That way, when we finally implement the "scramjet" technology, the facility where the new aircraft gets stored is safe from nuclear attacks by illegals who weren't able to enter the US through Mexico.
