Architect David Hertz paid $35,000 for a jumbo jet at a scrap dealer that specializes in old airplanes. Then he had to get permission from 17 different government agencies to turn it into a house — including the FAA, which needed to determine that pilots flying over it wouldn't mistake it for an airplane crash site.

The result is a California home that incorporates almost the entire plane (but does not look like a crash site in the least). The first class cabin, for example, became a guest house.
