On this day in engineering history, Kenneth A. Arnold became
the first American pilot to spot an unidentified flying object (UFO) - at least during the
Cold War. A respected businessman, Arnold claimed to see "a chain of nine peculiar
looking aircraft" while flying his CalAir A-2 near Mt. Rainier, Washington. Initially, the owner of the
Great Western Fire Control Supply Company "assumed" the mysterious aircraft "were
some type of jet plane". An experienced pilot, Arnold estimated their speeds
and reminded himself "that our army and air forces had planes that went that
fast". While watching the craft "flip and flash in the sun", however, Arnold became worried.
"The more I observed these objects", he later explained, "the more upset I
became."
As Kenneth Arnold flew in the direction of a snow-covered ridge
between Mt. Rainier
and nearby Mt. Adams, he used mountaintop points to estimate
that "the chain of these saucer-like objects were at least five miles long". As
the last object passed the southern-most crest of Mt. Adams,
he used an instrument-panel clock to determine that this craft had traveled
about 50 miles in one minute and forty-two seconds – a speed of 1700 mph. Next, using a Zeus
cowling fastener as a crude gauge, Arnold
compared the nine objects to a distant DC-4, estimating their size as slightly
smaller than 60 ft. Still looking for an identifiable tail, the experienced
pilot was disturbed that the unrecognizable aircraft were so flat that "their
thickness was about 1/20th their width". Moreover, the objects "did not appear
to me to whirl or spin but seemed in a fixed position traveling".
After landing in Yakima,
Washington, Kenneth A. Arnold told
his tale to a skeptical Al Baxter, the airport's general manager. The next day,
Arnold was
interviewed by reporters from the East
Oregonian newspaper in Pendleton. On June 27, 1957, papers across North
America began using the terms "flying saucer" and "flying disk" to describe
what Arnold
claimed to have seen. Although the pilot's story was corroborated by an eyewitness
who claimed to have viewed "round" objects from a small telescope on Mt. Adams,
many Americans reacted with fear and dismay. By June 28, Kenneth Arnold was
reported as saying, "I haven't had a moment of peace since I first told
the story."
