Since the public safety requires, and the advantages of uniform regulation make it desirable in the interest of aeronautical progress, that aircraft operating within the state should conform, with respect to design, construction, and airworthiness, to the standards prescribed by the federal government with respect to navigation of civil aircraft subject to its jurisdiction, it shall be unlawful for any person to operate or navigate any aircraft unless such aircraft has an appropriate effective license issued by the Federal Aviation Administration and is registered by the Federal Aviation Administration; provided, however, that this restriction shall not apply to military aircraft of the United States or possessions thereof, to public aircraft of any state or territory, or to aircraft licensed by a foreign country with which the United States has a reciprocal agreement covering the operation of such licensed aircraft.
