The ship was sighted a few times, briefly and without a good fix. It was spherical, the estimated diameter about twenty-seven miles, and was in an orbit approximately 3400 miles from the surface of the Earth. No one observed the escape from it.
The ship itself occasioned some excitement, but back there at the tattered end of the 20th century, what was one visiting spaceship more or less? Others had appeared before, and gone away discouraged--or just not bothering. 3-dimensional TV was coming out of the experimental stage. Soon anyone could have Dora the Doll or the Grandson of Tarzan smack in his own living-room. Besides, it was a hot summer.
The first knowledge of the escape came when the region of Seattle suffered an eclipse of the sun, which was not an eclipse but a near shadow, which was not a shadow but a thing. The darkness drifted out of the northern Pacific. It generated thunder without lightning and without rain. When it had moved eastward and the hot sun reappeared, wind followed, a moderate gale. The coast was battered by sudden high waves, then hushed in a bewilderment of fog.
Before that appearance, radar had gone crazy for an hour.
The atmosphere buzzed with aircraft. They went up in readiness to shoot, but after the first sighting reports only a few miles offshore, that order was vehemently canceled--someone in charge must have had a grain of sense. The thing was not a plane, rocket or missile. It was an animal.
If you shoot an animal that resembles an inflated gas-bag with wings, and the wingspread happens to be something over four miles tip to tip, and the carcass drops on a city--it’s not nice for the city.
The Office of Continental Defense deplored the lack of precedent. But actually none was needed. You just don’t drop four miles of dead or dying alien flesh on Seattle or any other part of a swarming homeland. You wait till it flies out over the ocean, if it will--the most commodious ocean in reach.
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.
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.
After a night and a day she abandoned that area, flying heavily eastward. The droning and swooping gnats of aircraft plainly distressed her. At first she had only tried to avoid them, but now and then during her eastward flight from St. Louis she made short desperate rushes against them, without skill or much sign of intelligence, screaming from a wide-open mouth that could have swallowed a four-engine bomber. Two aircraft were lost over Cincinnati, by collision with each other in trying to get out of her way. Pilots were then ordered to keep a distance of not less than ten miles until such time as she reached the Atlantic--if she did--when she could safely be shot down.
She studied Chicago for a day.
By that time Civil Defense was better prepared. About a million residents had already fled to open country before she came, and the loss of life was proportionately smaller. She moved on. We have no clue to the reason why great cities should have attracted her, though apparently they did. She was hungry perhaps, or seeking help, or merely drawn in animal curiosity by the endless motion of the cities and the strangeness. It has even been suggested that the life forms of her homeland--her masters--resembled humanity. She moved eastward, and religious organizations united to pray that she would come down on one of the lakes where she could safely be destroyed. She didn’t.
