U.S. Air Force to study use of Sierra Space ‘Ghost’ spacecraft to deliver cargo from orbit

Dropping supplies from orbit is an intriguing idea, but I wonder how practical it is, and for what type of situation it is deemed cost-effective. The article notes “critical supplies” and cites examples such as:

>Once fully developed, the spacecraft could be used for missions such as delivering rescue kits for downed pilots, medical supplies for disaster relief or logistical support for military operations.

But deorbiting to a location is not necessarily a quick response, it depends on where the satellites are in their orbit, so that “downed pilot” and “medical supplies” are probably going to be reached much quicker from land or sea, unless there is a constellation of supply satellites and that would surely cost a bomb!
