For a compact state, New Jersey has quite a few aviation facilities -- 475 to be exact, according to the state Department of Transportation. Of these, 314 are heliports, 75 are private-use airports and 44 are public airports. Two airports are international (Newark-Liberty and Atlantic City International), and they are the only two that handle general commercial flights. There are two military airbases: McGuire Air Force Base and Lakehurst Naval Air Engineering Station, also known as Maxfield Field. Eight other airports support corporate/executive flights and general aviation. The state has one seaplane base in Little Ferry. The only county without some sort of publicly used aviation facility is Hudson County. The first airport in the state was Bader Field, also known as Atlantic City Municipal Airport. It opened in 1912 and closed in 2006. Newark Airport opened in 1925 and is still one of the busiest airports in the country.
