The most advanced airship of that time had already completed its first round-the-world flight a year before its visit to Moscow. This giant machine circled over the city for two hours before landing at Khodynka Field. Since there were no landing facilities available, 200 cadets from military schools helped it land manually by pulling it down with ropes. With a length of 237 meters, a diameter of up to 30 meters, and a weight of 55 tons, the airship was equipped with five Maybach engines, each with 530 horsepower. It could carry 50 people on board and had the ability to fly non-stop for 14,000 kilometers. Even now it is impressive, and back then, it was even more so. At that time, Stalin was resting in the south, and his wife, Nadezhda Alliluyeva, wrote to him: "We were all entertained by the arrival of the Zeppelin in Moscow; the sight was truly worth attention. The whole of Moscow was looking at this remarkable machine. On the day of the Zeppelin's arrival, Vasya (Vasily Stalin) rode his bicycle from the Kremlin to the airfield through the entire city."
