She was 15 pounds below minimum weight for the Navy when she joined, but she had a mighty mind. Admiral Grace Hopper changed the Navy. And your world. She graduated from Vassar College in math and physics then took a doctorate from Yale in math. She joined the Navy in World War II because it needed mathematicians to build the massive machines that computed tables of distance, gun elevation, projectile weight, windage and other factors for precise naval gunnery. Almost immediately she saw something other mathematicians didn’t see: computers could talk. They weren’t just number crunchers to Grace. They could do much, much more if they were given a simple language that would bring the advantages of gigantic computing power and enormous data storage to common uses. While working on the early computers she developed a “compiler,” a kind of translating machine that turned plain-language needs into a set of mathematical commands that retrieved number data from storage banks, performed thousands or millions of math operations, and provided real-world answers. In 1959 she was crucial in devising the first broad-based computer language, COBOL (COmmon Business Oriented Language). It is the root of the many computer operating systems we use today. Then-Captain Grace worked with the National Bureau of Standards to develop self-testing capabilities so a computer could “de-bug” itself. She coined this word when she extracted a fried moth disrupting one of her computers. She led the Navy away from a few giant computers to interconnected, smaller, scattered computers, opening the door to the internet. You are reading plain language words from my small computer on your web-connected small computer. Thank you, Grace. In 1985, at 79, she was promoted to rear admiral of the United States Navy Reserve. She said, “The most important thing I've accomplished, other than building the compiler, is training young people. They come to me, you know, and say, 'Do you think we can do this?' I say, ‘Try it.’ And I back 'em up. They need that. I keep track of them as they get older and I stir 'em up at intervals so they don't forget to take chances.” She died in 1992 at 85. Admiral Grace Hopper received many awards and decorations but the Navy’s most sincere tribute came in 1996 when it named the guided missile cruiser DDG-70, USS Hopper. Naturally, its sailors call their ship “Amazing Grace.”
 Jan Adkins successfully tackles the art and science of 10,000 years of bridge building and imparts a lot of historical drama along the way. The process is given fascinating life in this accessible study, wonderfully illustrated by Jan Adkins himself. Ranging from ancient Rome to the present day, from simple log bridges to marvels of industrial technology, and from well-known landmarks to little-known feats of engineering and art, this book gives readers a new appreciation for that most familiar of structures, the bridge. Jan Adkins is a member of iNK's Authors on Call and is available for classroom programs through Field Trip Zoom, a terrific technology that requires only a computer, wifi, and a webcam.

 On Sunday morning, December 7, 1941, Cornelia Fort was doing something few people expected a woman to do. This 22-year-old was in a small two-seater plane, flying over Honolulu’s Pearl Harbor, teaching a student to fly. At that time, most people felt that flying was a “man’s job.” Cornelia had fallen in love with flying about two years earlier when, just for fun, she took a ride in a small plane. That ride changed her life. She took flying lessons and became such a good pilot that she was hired to teach others, one of the few flying jobs open to women in those days. On that sunny December 7 morning in 1941 in the skies over Pearl Harbor, something happened that changed her life yet again—and the lives of many others. Cornelia saw a military-type plane zoom straight at her. She pulled up on her plane’s controls to keep from being hit. She was accustomed to seeing military planes because there were U.S. Navy and Army bases nearby. But the plane that almost hit her wasn’t American. It had a big red circle on its wings—the symbol of Japan. Looking down, she saw smoke billow up from ships in Pearl Harbor. A squadron of foreign planes flew by. Something shiny dropped from one plane and exploded in the harbor. As Japanese fighter planes sprayed her plane with bullets, she skillfully managed to land safely at a nearby airport, She and her terrified student had just had a bird’s-eye view of Japan’s surprise attack on U.S. military ships and bases in Pearl Harbor, an attack that forced the U.S. to enter World War II. But the U.S. military wasn’t ready to fight air battles around the world. It didn’t have enough pilots. So it called on women to help. Cornelia joined the first women pilot’s unit to fly for the U.S. military, a group that became known as the WASPs--Women Airforce Service Pilots. They weren’t allowed to fly in combat overseas, but they handled much of the military flying in the U.S. Nevertheless, their missions were often dangerous. Sadly, through no fault of her own, in March 1943, Cornelia Fort became the first woman pilot to die flying for the U.S. military. The excellent job that she and the more than 1,100 other WASPs did showed that being a pilot could very well be a “woman’s job.” Click here for article sources.

Amy Nathan's book Yankee Doodle Gals tells the stories of many women who served as pilots from 1942 to 1944, including Jacqueline Cochran and Nancy Love, the true leaders of the WASPs. The history of the group, the hardships they faced, the obstacles they overcame, and what has transpired since the end of the war are supplemented by numerous photos that complement the text.

Two weeks before Halloween in 1944, a small jet fighter plane was parked on an Ohio airfield. The plane was wearing a kind of costume. It had fake propellers attached to the front of its wings. Was this jet getting dressed up so it could zoom off trick-or-treating at airports around the country? Not exactly. Those fake propellers weren’t a Halloween prank. They were serious business, a disguise that the Army hoped would fool enemy spies. Jet planes don’t use propellers, the spinning blades that give other aircraft the power to fly. A jet’s power comes from jet engines attached to the under side of its wings. A jet engine sucks in air and spins the air very fast inside the engine. The air is then mixed with gas fuel in the engine and an electric spark sets the gas-air mixture on fire. This burning mixture blasts out of the back of the engine with so much force that the plane can move forward and zoom up and away. In 1944, World War II was still raging. For most of the war, military planes had been propeller planes, both for the United States and Britain, as well as for their enemies, Nazi Germany and Japan. Jet engines had only been invented a few years before the war began but weren’t used in military planes until early 1944, when Germany became the first country to use a jet fighter in battle. The U.S. had built a jet plane—the XP-59A—but it was still being tested. In the fall of 1944, a version of this new jet, called the YP-59A, was shipped for testing to Wright Field, an Army aviation test center in Dayton, Ohio. To keep spies from finding out about the plane, it not only had fake propellers but also an armed soldier standing guard. On October 14, 1944, test pilots took turns test-flying this jet at Wright Field, after the fake propellers were removed! They noted problems, so none of these U.S. jets were ever used in the war. But although the plane never made history winning any battles, one of the pilots testing it did make history that October day: 26-year-old Ann Baumgartner Carl. That day she became the first American woman to pilot a jet aircraft. She was one of the WASP pilots--Women Airforce Service Pilots—the first women’s unit to fly for the U.S military.

I learned about the Caterpillar Club when I interviewed some flying WASPs—not the kind that buzz around on tiny wings. These WASPs were airplane pilots, the first women to fly for the United States military. They served during World War II: the Women Airforce Service Pilots (or WASP, for short). The Caterpillar Club they told me about was named for silkworm caterpillars that helped save pilots’ lives. If a plane developed engine trouble in midair, pilots could float to safety by using a parachute made from silk, a lightweight cloth that silkworm caterpillars help create. These caterpillars use a spit-like substance in their mouths to spin a long silk thread that they wrap around themselves, forming a cocoon that they live in for several weeks until they become moths. Those long silk threads can then be unwound from the cocoons and woven together to make silk cloth. About twenty years before World War II, a parachute company started the Caterpillar Club for people whose lives were saved by using a parachute to escape from a disabled plane. People could write to the company about their parachute rescue, pay a membership fee, and the company would send them a little caterpillar pin. However, the WASP pilots I spoke with said that some pilots liked to feel they were part of the Caterpillar Club even if it wasn’t an aircraft’s fault that led them to use a parachute. During World War II, pilots—both men and women—trained to fly military aircraft for the Army in small open planes. The planes didn’t have a roof. If a nervous pilot-in-training forgot to buckle the seat belt and the plane tipped over, the pilot could fall out! Fortunately, they always wore a parachute. Landing safely—thanks to the parachute—not only let them feel part of the Caterpillar Club, but also helped the students remember to never, ever forget to buckle up again. However, by World War II, many parachutes used by U.S. pilots weren’t made of silk. The silk-producing areas of the world were controlled then by Japan, which the U.S. was fighting in this war. Because U.S. companies could no longer get silk cloth, they began making parachutes from a new material scientists had just invented—nylon. Most parachutes are made of nylon today. Even so, the Caterpillar Club lives on. Click here for source notes on this article.

Courtesy National Archives  If you are interested in finding out more about the WASPs, Amy Nathan has written a book on the subject. Through firsthand accounts, she tells how these early pilots they test-flew newly repaired aircraft, dragged banners behind their planes so male trainees could practice shooting moving targets with live ammunition (!), and ferried all kinds of aircraft from factories to military bases. Yankee Doodle Gals will give you a new look at World War II and show you just how dramatically society has changed since then. Click here for more information. MLA 8 Citation Nathan, Amy.
