what do the blue and red flags mean in skiing
Slalom skiing A course is constructed by laying out a series of gates, formed by alternating pairs of red and blue poles. The skier must pass between the two poles forming the gate, with the tips of both skis and the skier's feet passing between the poles. A course has 55 to 75 gates for men and 40 to 60 for women. The vertical drop for a men's course is 180 to 220 m (591 to 722 ft) and slightly less for women.[4] The gates are arranged in a variety of configurations to challenge the competitor.
Emblems of the International Red Cross and Red Crescent Movement In popular culture, the red cross symbol came to be a recognisable generic emblem for medicine, commonly associated with first aid, medical services, products, or professionals; it has been misused in toys, movies, and video games, outside its defined context. After objections from the Movement, derivatives and alternatives are used. Johnson & Johnson had registered the symbol for their medicinal products. The appropriation of the symbol has led to further confusion when first aid teams and ski patrols in the United States reverse the symbol–a white cross on a red background–thus suggesting an affiliation with Switzerland by simply re-applying the original idea of the red cross symbol, namely by reversing the red cross symbol's colors.[1][2][3][4]
