By 1919, dirigibles were of course well known to most of the world. When a dirigible-shaped object appeared over Huntington, West Virginia, in July of that year, there was no great alarm. It was believed to be an American blimp, though the darkness—it was eleven at night—prevented observers from being sure. But a later check-up proved it was not an American ship, nor was it from any country possessing such craft. For some time after this, there were few authentic reports. Then in 1934, Nicholas Roerich, head of the American-Roerich expedition into Tibet, had a remarkable experience that bears on the saucer riddle. On pages 361 and 362 of his book _Altai Himalaya_, Roerich describes the incident. The expedition party was in the wilds of Tibet one morning when a porter noticed the peculiar actions of a buzzard overhead. He called Roerich’s attention to it; then they all saw something high in the sky, moving at great speed from north to south. Watching it through binoculars, Roerich saw it was oval-shaped, obviously of huge size, and reflecting the sun’s rays like brightly polished metal. While he trailed it with his glasses, the object suddenly changed direction, from south to southwest. It was gone in a few moments. This was the last sighting listed before World War II. When I had finished, I stared out the plane window, curiously disturbed. Like most people, I had grown up believing the earth was the center of everything—life, intelligence, and religion. Now, for the first time in my life, that belief was shaken. It was a curious thing. I could accept the idea that we would eventually explore space, land on the moon, and go on to distant planets. I had read of the plans, and I knew our engineers and scientists would somehow find a way. It did not disturb my belief in our superiority. But faced with this evidence of a superior race in the universe, my mind rebelled. For years, I had been accustomed to thinking in comic-strip terms of any possible spacemen—Buck Rogers stuff, with weird-looking space ships and green-faced Martians. But now, if these sightings were true, the shoe was on the other foot. We would be faced with a race of beings at least two hundred years ahead of our civilization—perhaps thousands. In their eyes, we might look like primitives. My conjectures before the take-off had just been idle thinking; I had not really believed this could be the answer. But now the question came back sharply. How would we react to a sudden appearance of space ships, bringing that higher race to the earth? If we were fully prepared, educated to this tremendous adventure, it might come off without trouble. Unprepared, we would be thrown into panic.
