PENDLETON, Ore., June 26?Army and CAA spokesmen expressed skepticism today over a report of nine mysterious objects?whizzing at 1200 miles an hour.
Kenneth Arnold, a flying Boise, Idaho, businessman who reported seeing them, clung, however, to his story of the shiny, flat objects, each as big as a DC-4 passenger plane, racing over Washington's Cascade Mountains with a peculiar weaving motion
like the tail of kite.
An Army spokesman in Washinton, D. C., commented,
as far as we know, nothing flies that fast except a V-2 rocket, which travels at about 3,500 miles an hour?and
that's too fast to be seen.
The spokesman said no high-speed experimental tests were being made in the area where Arnold said the objects were.
Mr. Arnold described the objects as
flat like a pie-pan, and so shiny that they reflected the sun like a mirror. He said he was flying east a 2:59 p. m. two days ago toward Mt. Rainier when they appeared directly in front of him 25-30 miles away at 10,000 feet altitude.
By his plane's clock he timed them at 1:42 minutes for the 47 miles from Mt. Rainier to Mt. Adams, Arnold said, adding that he later figured by triangulation that their speed was 1,200 miles an hour.
I know I never saw anything so fast, he said.
At first he thought they were geese, but quickly saw they were too big?as big as a DC-4 that was about 20 miles away, he said. The DC-4 pilot reported nothing unusual sighted. Then Mr. Arnold said he thought of jet planes and started to clock them,
but their motion was wrong for jet jobs.
I guess I don't know what they were?unless they were guided missiles, said Arnold, who continued here on a business trip.
