Also, to circumvent the aeronautical regulatory issues of unmanned flight in civilian airspace, manned stratospheric HAPs are attracting considerable attention, as an intermediate evolutionary step. A third line of thinking, especially by entrepreneurs, is to just go ahead and build HAPs and fly them in a suitable environment (or friendly country) and let the regulations catch up with reality, giving them a head start on any competition. There is some precedent for this; anecdotally the development of the direct broadcast by satellite (DBS) market in the UK by Sky TVin the 1980s shows what is possible by just going ahead and developing a product.
The SkyStation concept was ahead of the technology, especially the airship technology, of the time. Angel Technologies aircraft technology was more conventional, but the communications technology and capability claims were over ambitious, resulting in a failure of the business model. Both the technology and business model design are discussed in later chapters. In Asia at the same time, both Japan and Korea decided to start up their own projects. Japan put significant funding into their activities through a millennium project initiative that commenced in 1998, with the primary splits being between aeronautics, telecommunications, and earth observation.
