On December 11, 1958, 250 km from the Belgian Antarctic station "King Baudouin," a plane with an expedition on board crashed. Among the participants was Prince Antoine de Lannoy. Soviet polar explorers at the "Mirny" station offered help to the Belgians. Yes, our countries were not allies, quite the opposite. However, in Antarctica, Soviet polar explorers strictly adhered to the law of mutual aid and had repeatedly helped foreign travelers. A team of Soviet Antarctic researchers, led by Viktor Perov, set out on the search. They had to operate in a nearly unexplored area of Antarctica, in extremely difficult weather conditions, with no accurate maps. Even radio communication was unreliable. The search lasted almost four days, and eventually, Perov and his team found the tent where the Belgians were sheltering. This feat was not forgotten in Belgium: in 1959, Perov was awarded the Order of Leopold II, and many years later, in 2001, he was awarded the Order of the Crown.
