Something i find most exciting is the plasticity of "Rutan's"construction techniques.The adaptive potentials allow relatively small groups the potential to Model space exploration craft.This ability to compose and test workable designs ,through relatively short time frames,demanding far reduced man hours,...will unleash the imaginations/potentials/realities that ---were--- in the past owned by the politics of the ---only--- game in town "NASA" . An example might be a second generation "Searl"type device encapsulated in a composite type air/space frame.Such a device might rise slowly off ones back patio,..to park in geosynchronous orbit.After that,...WOW!,...so a very interesting time to play,...no?
