A day of grandparents, animation, judo and locomotive whistle. We will start the morning with the celebration of Grandparents' Day. The date was not chosen by chance, since at the end of October our ancestors celebrated the grandfathers in the fall - a holiday designed to strengthen ties with the ancestors and unite all generations. So don't forget to write or say kind words to your grandparents. And for our part, we wish everyone health and longevity. Today is a holiday for the Russian Army, as the Day of the Establishment of the Russian Army Aviation is celebrated. On this day in 1948, the first aviation squadron equipped with helicopters was established in Serfutsov near Moscow. Now this aviation is designed to solve operational-tactical and tactical tasks during military operations, including the Northern Military District. Today is a good reason to watch some cartoon, thus celebrating International Animation Day. The founder of this genre is considered to be the French artist and inventor Emile Raineau, who on October 28, 1892 demonstrated his perxinoscope mechanism - he showed moving images. Even the word animation itself comes from French and translates as animation. What is your favorite cartoon? And on this day World Judo Day was celebrated. Judo is translated from Japanese as "the gentle way". Techniques from classical judo are used in successful martial arts for self-defense, such as sambo. This sport appeared in 1882. In 1964, a historic event took place - judo was included in the program of the Olympic Games. Today there are about 180 countries in the International Judo Federation. "Poo-poo": today is also the day of the locomotive whistle. A long locomotive whistle is a sound that is hard to confuse with anything else: it contains the road, the farewell on the platform and the promise of new cities.
