floating airport
A floating airport is an airport built and situated on a very large floating structure (VLFS) located many miles out at sea utilizing a flotation type of device or devices such as Pneumatic Stabilized Platform (PSP) technology.
As the population increases and land becomes more expensive and scarce, very large floating structures (VLFS) such as floating airports could help solve land use, pollution and aircraft noise issues.
==Early History==
The first discussion of a floating airport was for trans-Atlantic flights. At that time a passenger aircraft capable of making the trip could be built but because of the massive need for fuel for the flight, it had a limited payload. An article appeared in January 1930 issue of ''Popular Mechanics'' in which a model of a floating airport located in the Atlantic was proposed. To make safe flight possible with the aviation technology of that time, it called for eight such airports in the Atlantic. But unlike future floating airport ideas which were free floating, this 1930 concept had a floating airport platform, but with stabilizer legs which prevent the flight deck from pitching and rolling, similar in concept to some of today's off shore oil rigs. The cost of establishing eight such floating airports in 1930 was estimated at approximately $12,000,000 dollars 〔 ("Sea Legs of Floating Airport Prevents Rolls and Pitches" ''Popular Mechanics'', January 1930 ) Article and photo located bottom-right-side of page〕 The idea of floating airports was forgotten until in 1935 the famous French aviation pilot and builder Bleriot gave one of his last interviews in which he made the case for floating airports in mid-Atlantic; he called them Seadromes as a solution to economical trans-Atlantic passenger flights.〔 ("SEADROMES! Says Bleriot" ''Popular Mechanics'', October 1935 )〕
