A Cessna 172 glows in a condo's plane port at the end of a day. The number of private pilots in the US has declined steadily in recent decades, down 45% since 1980, according to FAA data compiled by the Aircraft Owners and Pilots Association. Meanwhile, the cost of general aviation continues to climb. Despite those trends, resident Fred Silverio, a real estate agent at Karlhaus Realty, said he doesn't foresee demand for hangar homes going away. "The last few houses I've sold have been to foreign pilots and families who are coming to the US for the freedom of flight. You just can't fly the distances [in some countries] that you can here," he said, referring to the roughly 20,000 airports across the US, "And you don't have to get a flight plan filed days in advance with the government."John Brecher / NBC News
