It might be a bolide -- a large , slow-moving meteorite . It was n't likely , but the entire report was improbable . The message reached the Military Information Center in Denver at 8:05 A.M. By 8:06 it had been relayed to Washington and every plane on the Pacific Coast was ordered aloft . The Oregon radar unit reported the same object at 8:07 A.M. . It said the object was seven hundred fifty miles high , four hundred miles out at sea , and was headed toward the Oregon coastline , moving northwest to southeast . There was no major city in its line of travel . The impact point computed by the Oregon station was nowhere near South Dakota .
