Harold E. Thompson (chemist)

Harold E. "Tommy" Thompson (1921 – October 29, 2003 of Hobart, Indiana, was a helicopter aviation pioneer. He was the first man to intentionally loop a helicopter, set three international helicopter speed records, and was the first man to land a helicopter in the courtyard of The Pentagon. Thompson was a veteran of 3,500 hours in single-engine propeller fixed-wing aircraft and 3000 more in helicopters.

Life

Having spent two years at Purdue University, Thompson was called up into the United States Army Air Forces in 1943, a week after he had married his childhood sweetheart, Carolyn Kramer. Thompson served as a P-47 instructor at Moore Field in Mission, Texas, until January 1945, when he earned an assignment to the Army's first helicopter class at Chanute Field, Illinois. Later, he was assigned to the Bridgeport, Connecticut, plant of Igor Sikorsky, who pioneered helicopters in America.

After the war, "Tommy" as he was known, got a job as one – and with 28 the youngest – of Sikorsky's three test pilots—in the trial and error days. The plant produced six helicopters a month, mostly hand built. Engineers tinkered with new designs, and the test pilots tried them out. Most of the early models had slow, sluggish controls - some flew as expected, but others didn't. Thompson was also Igor Sikorsky's personal pilot. By 1949, Thompson was an experienced helicopter pilot. He had been through some forced landings and crashes, but had not been seriously injured.

Records set in the S-52-1

Starting in late 1945 Sikorsky engineers developed the Sikorsky S-52 helicopter, its prototype flew first in 1947.

"It was a sharp, responsive dream," Thompson recalls. "After trying some mild acrobatics, I figured it would loop." Until Thompson, no one had dared try to loop a helicopter. As Sikorsky's chief test pilot Jimmy Viner pointed out, "Any of 10 things can go wrong--all fatal, be sure you know what you're doing." Thompson did—erratically at first, then perfectly—10 loops in all, as a 8 mm movie camera recorded the flight at Bridgeport, Connecticut on May 9, 1949, for history.

That year, he went to the Cleveland air races with the S-52, where he set the first of three international speed records that he was to achieve in the helicopters: over .

Flight instructor

Thompson also taught others how to fly helicopters. His students included Admiral Arthur W. Radford; Pat Handy, first woman to fly solo in a helicopter; and Rodman Wanamaker, Eastern department store tycoon.

Last flight

His career came to an abrupt halt on a spring day in 1950, when he took an admiral aloft at the Navy's Lakehurst, New Jersey
