I can't see video on this computer (dialup, eh) but if you're pushing some sort of common supersonic travel, the West has already spent that nut. The primary Western Empire is now far more interested in achieving a condition of domestic economic slavery and foreign political supremacy. Remember the Concorde? Yeh, the West has officially kissed that capability good bye, preferring to commit hundreds of billions towards beating into submission Arabs and Persians who just happen to live above oil deposits.
