...But So Far It's Floundering
In San Diego, the 32 members of the airport study group found obstacles at every site -- immovable mountains, or too many people, or environmental conflicts. They also wanted the airport to be convenient for people to drive to, without being too close to where those people actually live, which sounds great if you can make it work. While they couldn't find anything really objectionable about the ocean site, the trouble is that it's never been done. The Japan project worked, but after testing it was abandoned and the runway was disassembled. A few parts became fishing parks, another is a floating parking lot, and most of it was scrapped. Last year, the developers proposed using the technology to expand Tokyo's Haneda Airport, but that project has stalled over financing issues.
