A student form Kyiv, Iryna, gave her beloved young man a romantic gift for the St. Valentine`s Day – a flight for two in the hot-air balloon. However, the red 2550 cubic meter envelope of the aircraft was shaped for the flight as an image of a heart. This made it the largest Valentine`s Day card which has ever flown in the air of the country. Vlad Klimenko was the pilot of the hot-air balloon.
