At the end of 1957, the AN-12 paratroop transport airplane designed for transportation of troops, military and fighting equipment weighting up to 20 tons performed its first flight. Being one of the best airplanes of such category in the world, the Antonov AN-12 became the basic airplane of the Soviet Union military transport aviation, and it had flying range up to 6,000 km. The airplane has proven itself well in India, in high-altitude and poorly adapted aerodromes. In total for the period from 1957 to 1972, 1243 AN-12 aircraft of various modifications were manufactured.

Why is this troop transport plane doing in the US, is not to drop off Ukrainian troops on our soil? They are leaving from Cali, and I assume they are going back to Ukraine.
