on a regular basis. The airport regained its commercial operations, initially serving domestic flights, mostly to single customers, on Piper Cub aircraft. It later expanded operations to scheduled service on larger aircraft to various parts of Israel. As a result of the land availability, an additional, north–south, runway was built with no opposition. By 1960, land in Tel Aviv became scarce, and the municipality demanded that the airport be relocated northward, so as to allow residential development in its place. However, a committee that investigated in 1961 the options for such a relocation found no feasible site in proximity to Tel Aviv and suggested that flights be moved to Lod airport (now known as Ben Gurion Airport), and that road access from Tel Aviv to Lod be improved. This option, however, was blocked by the Israel Defense Forces. The government set up a second committee in 1968 who suggested that the old east–west runway be closed and the airport's area reduced, allowing for development to the east of the airport. They suggested that this is replaced by a new runway in the sea, adjacent to the beach. The runway was closed, and a high density upper-middle income neighborhood was built to the east of the airport, although the new runway was never constructed due to the high cost involved. As the new residential area suffered from aircraft noise, residents joined in the demand that the airport be relocated. Despite this, the number of flights to the airport increased as the newly formed Israel Airports Authority strived to reduce congestion at Ben Gurion Airport by shifting all domestic turbo-prop flights to Sde Dov. Once again, the only feasible alternative proposed at this point was to build a runway in the sea and again, the high cost of this project meant that it never happened. This was a large issue in the area during the whole of the 1980s. Recent history and closure The early 1990s saw a rapid rise in land values in the Tel Aviv area following the massive immigration wave from the former Soviet Union and the rapid economic growth fueled by Israel's subsequent hi-tech boom. This brought the issue of relocation back to light. Despite this, however, in 1997, Sde Dov was declared an International Airport for private flights. The issue remained unresolved until late 2006 when it was announced that the airport would be vacated to make
