I have an interesting concept for a story, but that's really about it: no ideas for a plot or even characters. Some of you may be aware NASA possesses a small fleet of military aircraft including fighter jets (for astronaut training, aerospace research, and as "chase planes" to document flight tests) and a bomber (as a launch platform for rockets and experimental aircraft). My idea has these aircraft, still painted with NASA colors, serving as the backbone of a planetary defense force. Based out of Dryden Flight Research Center inside Edwards Air Force Base, California; NASA's defense force would consist of jet fighters, bombers, aerial tankers, radar planes, and transport planes; and would be painted with NASA colors and emblems so as to appear as research aircraft. A typical mission would involve a radar plane picking up an alien space ship on an approach to Earth, and the bombers launching modified Pegasus booster rockets (small rockets launched from aircraft that can reach space) that will home in on the intruders to destroy them with nuclear weapons. The fighters would fly escort to protect the bombers and radar planes from alien ships that manage to enter the atmosphere, and would provide defense for the research center. Various anti-aircraft missiles, private contractors, and Air Force security personnel would provide a last line of defense for ground installations from both aerial attack or a landing. For training, NASA units would use National Guard units equipped with the latest and most advanced fighter aircraft (for defense against alien ships that got past the NASA defenses) to simulate an attacking force. I suppose some possible plots would include explaining how such a force would come to be, and why it would be kept secret (which could open up some conflicts in a nation where everyone is about cutting spending for non-essential programs). Another possible idea would be constructing a scenario where these units would be used in combat, e.g. an alien attack. However, I have not developed these very much, nor do I have any characters to work with. I am not sure what the best way to proceed would be.
