On This Date In History

On May 15, 1941, the jet-propelled Gloster-Whittle E 28/39 aircraft flies successfully over Cranwell, England, in the first test of an Allied aircraft using jet propulsion. The aircraft’s turbojet engine, which produced a powerful thrust of hot air, was devised by Frank Whittle, an English aviation engineer and pilot generally regarded as the father of the jet engine.
Whittle, born in Coventry in 1907, was the son of a mechanic. At the age of 16, he joined the Royal Air Force (RAF) as an aircraft apprentice at Cranwell and in 1926 passed a medical exam to become a pilot and joined the RAF College. He won a reputation as a daredevil flier and in 1928 wrote a senior thesis entitled Future Developments in Aircraft Design, which discussed the possibilities of rocket propulsion.
From the first Wright brothers flight in 1903 to the first jet flight in 1939, most airplanes were propeller driven. In 1910, the French inventor Henri Coanda built a jet-propelled bi-plane, but it crashed on its maiden flight and never flew again. Coanda’s aircraft attracted little notice, and engineers stuck with propeller technology; even though they realized early on that propellers would never overcome certain inherent limitations, especially in regard to speed.
After graduating from the RAF college, Whittle was posted to a fighter squadron, and in his spare time he worked out the essentials of the modern turbojet engine. A flying instructor, impressed with his propulsion ideas, introduced him to the Air Ministry and a private turbine engineering firm, but both ridiculed Whittle’s ideas as impractical. In 1930, he patented his jet engine concept and in 1936 formed the company Power Jets Ltd. to build and test his invention. In 1937, he tested his first jet engine on the ground. He still received only limited funding and support, and on August 27, 1939, the German Heinkel He 178, designed by Hans Joachim Pabst von Ohain, made the first jet flight in history. The German prototype jet was developed independently of Whittle’s efforts.
One week after the flight of the He 178, World War II broke out in Europe, and Whittle’s project got a further lease of life. The Air Ministry commissioned a new jet engine from Power Jets and asked the Gloster Aircraft Company to build an experimental aircraft to accommodate it, specified as E 28/39. On May 15, 1941, the jet-propelled Gloster-Whittle E 28/39 flew, beating out a jet prototype being developed by the same British turbine company that earlier balked at his ideas. In its initial tests, Whittle’s aircraft, flown by test pilot Gerry Sayer, achieved a top speed of 370 mph at 25,000 feet, faster than the Spitfire or any other conventional propeller-driven machine.
As the Gloster Aircraft Company worked on an operational turbojet aircraft for combat, Whittle aided the Americans in their successful development of a jet prototype. With Whittle’s blessing, the British government took over Power Jets Ltd. in 1944. By this time, Britain’s Gloster Meteor jet aircraft were in service with the RAF, going up against Germany’s jet-powered Messerschmitt Me 262s in the skies over Europe.
Whittle retired from the RAF in 1948 with the rank of air commodore. That year, he was awarded 100,000 pounds by the Royal Commission on Awards to Inventors and was knighted. His book Jet: The Story of a Pioneer was published in 1953. In 1977, he became a research professor at the United States Naval Academy in Annapolis, Maryland. He died in Columbia, Maryland, in 1996.

On May 15, 1756, the Seven Years War, a global conflict known in America as the French and Indian War, officially begins when England declares war on France. However, fighting and skirmishes between England and France had been going on in North America for years.
In the early 1750s, French expansion into the Ohio River valley repeatedly brought France into armed conflict with the British colonies. In 1756, the first official year of fighting in the Seven Years War, the British suffered a series of defeats against the French and their broad network of Native American alliances. However, in 1757, British Prime Minister William Pitt (the older) recognized the potential of imperial expansion that would come out of victory against the French and borrowed heavily to fund an expanded war effort. Pitt financed Prussia’s struggle against France and her allies in Europe and reimbursed the colonies for the raising of armies in North America.
By 1760, the French had been expelled from Canada, and by 1763 all of France’s allies in Europe had either made a separate peace with Prussia or had been defeated. In addition, Spanish attempts to aid France in the Americas had failed, and France also suffered defeats against British forces in India.
The Seven Years War ended with the signing of the treaties of Hubertusburg and Paris in February 1763. In the Treaty of Paris, France lost all claims to Canada and gave Louisiana to Spain, while Britain received Spanish Florida, Upper Canada, and various French holdings overseas. The treaty ensured the colonial and maritime supremacy of Britain and strengthened the 13 American colonies by removing their European rivals to the north and the south. Fifteen years later, French bitterness over the loss of most of their colonial empire contributed to their intervention in the American Revolution on the side of the Patriots.

On May 15, 1942, a bill establishing a women’s corps in the U.S. Army becomes law, creating the Women’s Auxiliary Army Corps (WAACs) and granting women official military status.
In May 1941, Representative Edith Nourse Rogers of Massachusetts, the first congresswoman ever from New England, introduced legislation that would enable women to serve in the Army in noncombat positions. Rogers was well suited for such a task; during her husband John J. Rogers’ term as congressman, Rogers was active as a volunteer for the Red Cross, the Women’s Overseas League, and military hospitals. Because of her work inspecting field and base hospitals, President Warren G. Harding, in 1922, appointed her as his personal representative for inspections and visits to veterans’ hospitals throughout the country. She was eventually appointed to the Committee on Veterans’ Affairs, as chairwoman in the 80th and 83rd Congresses.
The bill to create a Women’s Auxiliary Army Corps would not be passed into law for a year after it was introduced (the bombing of Pearl Harbor was a great incentive). But finally, the WAACs gained official status and salary, but still not all the benefits accorded to men. Thousands of women enlisted in light of this new legislation, and in July 1942, the “auxiliary” was dropped from the name, and the Women’s Army Corps, or WACs, received full Army benefits in keeping with their male counterparts.
The WACs performed a wide variety of jobs, “releasing a man for combat,” as the Army, sensitive to public misgivings about women in the military, touted. But those jobs ranged from clerk to radio operator, electrician to air-traffic controller. Women served in virtually every theater of engagement, from North Africa to Asia.
It would take until 1978 before the Army would become sexually integrated, and women participating as merely an “auxiliary arm” in the military would be history. And it would not be until 1980 that 16,000 women who had joined the earlier WAACs would receive veterans’ benefits.

On May 15, 1800, President John Adams orders the federal government to pack up and leave Philadelphia and set up shop in the nation’s new capital in Washington, D.C.
After Congress adjourned its last meeting in Philadelphia on May 15, Adams told his cabinet to make sure Congress and all federal offices were up and running smoothly in their new headquarters by June 15, 1800. Philadelphia officially ceased to serve as the nation’s capital as of June 11, 1800.
At the time, there were only about 125 federal employees. Official documents and archives were transferred from Philadelphia to the new capital by ship over inland waterways. President and Mrs. Adams did not move in to the (unfinished) president’s mansion until November of that year. Settling in to the White House was a challenge for the new first lady. In December, Abigail Adams wrote to a friend later she had to line-dry their clothes in what eventually became the East Room.
