Semper Fly: Marines in Space
A proposed suborbital space transport will put boots on the ground anywhere in the world in two hours or less. But can it overcome huge technological—and political—hurdles?

As any battlefield commander will tell you, getting troops to the fight can be as difficult as winning it. And for modern-day soldiers, the sites of conflict are so far-flung, and the political considerations of even flying over another country so complicated, that rapid entry has become nearly impossible.
If a group of Marine Corps visionaries have their way, however, 30 years from now, Marines could touch down anywhere on the globe in less than two hours, without needing to negotiate passage through foreign airspace. The breathtaking efficiency of such a delivery system could change forever the way the U.S. does battle.
