Описание закладки:
AMA sanctions more than 2, 000 model competitions throughout the country each year and certifies official model flying records on a national and international level. Additionally, AMA is the chartering organization for more than 2, 500 model airplane clubs across the country, offering its chartered clubs official contest sanctions, insurance, and assistance in getting and keeping flying sites. When the balloon that is carrying the plane gets high enough, it will inevitably burst as the gas inside expands beyond the ability of the balloon to contain it. When that happens, Helium is very expensive in Sweden, so Windestеl instead used highly flammable hydrogen to inflate his balloon. If hydrogen in balloons sounds familiar, that’s probably because the tangle of balloon risks getting in the way of the radio antenna and covering the camera.
