The two-day Wonsan International Friendship Air Festival was held at the newly refurbished Kalma Airport -- previously a military airfield -- completed last year to boost tourism in the area around the eastern port city of Wonsan.
The festival was already scheduled before North Korea conducted its fifth nuclear test on September 9, triggering international outrage and threats of still further sanctions against the deeply isolated nuclear-armed country.
The show kicked off with an aerial display by a US Hughes MD-500 military helicopter -- one of a number acquired in the 1980s by using a third country to circumvent US export restrictions.
The provisions prevent member states selling or supplying North Korea with aviation fuel, aviation gasoline or naptha-type jet fuel or kerosene type jet fuel.

But a recent report by the Nautilus Institute for Security concluded that domestic supply of jet fuel was probably adequate to keep air force aircraft flying, especially given their very low annual exercise rate.
The Hughes helicopter was followed by an extended solo acrobatic display by the most advanced aircraft in the North Korean air force -- an early-model Soviet built Mikoyan MiG-29 Fulcrum which made several ear-splitting low passes over the crowd.
North Korean airports are generally high security areas, but the Kalma tarmac and surrounding airfield were opened for the festival to several thousand local spectators, foreign media and several hundred slightly over-excited aviation enthusiasts from 20 countries.
Several foreign observers noted that the low passes by the MiG29 and later by a Sukhoi-25 fighter would have been forbidden at other international air festivals.
