After our sightseeing flight, many people had quickly gotten off after taking a few photos in the cockpit. They made a dash towards the terminal and I was puzzled why they were doing that. Soon I realized that there was a puddle of water there, which was the result of the cooling of brakes, a standard procedure for the Russian jets in North Korea. And there we were; 10-15 people flat on a concrete apron in one of the most isolated countries in the world. Must've been a sight!
