The numbers for changing SpaceShipOne into a fighter and then mass-producing them are so low that to print them only invites idle laughter.
What can't be denied is that even hand-building them from scratch is cheap...that they go higher than anything that anyone has...and that they are faster.
Not bad for civilians.
In the meantime, pork projects like the F-22 and F-35 divert our attentions and resources away from going sub-orbital.
Civilians can go sub-orbital but our military can't. We haven't seen this sort of technological discrepancy since the Wright brothers had the ability to fly over forts before our military could duplicate the feat.
