DARPA and four-dimensional navigation

Two unmanned aircraft were able to make history this month when they
joined up in a preset formation using the same mission plan. Both aircraft maintained their position relative to a simulated third aircraft that was considered the “virtual lead.” This unprecedented demonstration was enabled by the X-45A’s four-dimensional navigation capability, the ability to position a vehicle at a particular location in space at a designated time. this demonstration creates a whole new spin on precision. The ability to so accurately define a flight plan with no pesky pilots in the way is dream of any General. No longer does the Pentagon have to worry about the social back lash from downed pilots in battle and can now preplan a surgical strike with the air crew safely seated at virtual controls miles away from the actual flight. Tom Cruise better play some more Xbox if he wants to remain Top Gun.
