It, or rather she, didn't go back over the Pacific, perhaps because of the prevailing westerlies. After the Seattle incident she climbed to a great altitude above the Rockies, apparently using an updraft with very little wing-motion. There was no means of calculating her weight, or mass, or buoyancy. Dead or injured, drift might have carried her anywhere within one or two hundred miles. Then she seemed to be following the line of the Platte and the Missouri. By the end of the day she was circling interminably over the huge complex of St. Louis, hopelessly crying. [Illustration] She had a head, drawn back most of the time into the bloated mass of the body but thrusting forward now and then on a short neck not more than three hundred feet in length. When she did that the blunt turtle-like head could be observed, the gaping, toothless, suffering mouth from which the thunder came, and the soft-shining purple eyes that searched the ground but found nothing answering her need. The skin-color was mud-brown with some dull iridescence and many peculiar marks resembling weals or blisters. Along the belly some observers saw half a mile of paired protuberances that looked like teats. She was unquestionably the equivalent of a vertebrate. Two web-footed legs were drawn up close against the cigar-shaped body. The vast, rather narrow, inflated wings could not have been held or moved in flight without a strong internal skeleton and musculature. Theorists later argued that she must have come from a planet with a high proportion of water surface, a planet possibly larger than Earth though of about the same mass and with a similar atmosphere. She could rise in Earth's air. And before each thunderous lament she was seen to breathe. It was assumed that immense air sacs within her body were inflated or partly inflated when she left the ship, possibly with some gas lighter than nitrogen. Since it was inconceivable that a vertebrate organism could have survived entry into atmosphere from an orbit 3400 miles up, it was necessary to believe that the ship had briefly descended, unobserved and by unknown means, probably on Earth's night-side. Later on the ship did descend as far as atmosphere, for a moment ... St. Louis was partly evacuated. There is no reliable estimate of the loss of life and property from panic and accident on the jammed roads and rail lines. 1500 dead, 7400 injured is the conservative figure.
