Start Your Aircraft Engines!: Aviation Accomplishments in Speedway During World War II

Note: For those interested in learning more about aviation in the Speedway area during World War I, see “Speedway: An Aviation Hub During World War I.”

This weekend, some 300,000 fans are expected to descend upon the Town of Speedway to watch the 102nd running of the Indianapolis 500. The Speedway area has been home to the “Greatest Spectacle in Racing” since 1911. The race attracted drivers and fans from all over the world. It has only been cancelled on two occasions: during World War I (1917-1918) and World War II (1942-1945). While there was no roar of race cars, the area was by no means quiet. Instead, the Speedway area became a hub for wartime production, with aircraft engines taking center stage.

Entrepreneur and Indianapolis Motor Speedway co-founder James Allison quite literally shifted gears when he devoted his precision machine shop’s resources on Main Street, just south of the track, to the war effort in 1917. Allison originally built the shop to redesign and rebuild foreign and domestic racecars. By mid-1918, the War Department awarded government contracts to Allison Experimental Company to build parts for the Liberty aircraft engine. According to the National Museum of the United States Air Force, the Liberty represented “America’s major technological contribution to World War I.” The United States’ auto industry produced over 20,000 of these engines during the war and Allison’s Speedway company played its part in this endeavor. The Speedway area also saw the development of an aviation repair depot where workers helped repair, modify, and test hundreds of airplanes and aircraft engines.

Just one month after the war’s end, in December 1918, the owners of the Indianapolis Motor Speedway announced that the Indianapolis 500 would resume in May 1919. The focus in the Speedway area quickly shifted back to automobiles and racing, but interest in aviation there had just begun. During the 1920s, Allison Experimental Company (Allison Engineering Company by 1921) worked on rebuilding and inverting Liberty engines.

Following James Allison’s death in 1928, General Motors Corp. filed an appropriation request to buy the company the following year. According to the request, General Motors planned to continue Allison’s work in the aviation industry. The Indianapolis Chamber of Commerce promoted the acquisition, stating that with General Motors’ purchase of the company:

Development of this city as a center for the nation’s aviation industry seems assured.

The Chamber of Commerce was not far off the mark. During the 1930s, Allison Engineering Co. focused its efforts on developing a 1,000 horsepower liquid-cooled aircraft engine in the Speedway area. Known as the V-1710, it would become the primary engine that powered Allied fighter aircraft during World War II. Norman Gilman, chief engineer and general manager for the company, reasoned that a liquid-cooled engine could be placed inside the fuselage, where a radial type engine could not and therefore developed high wind resistance or drag, particularly at higher speeds. Despite initial hesitation from both the U.S. Navy and U.S. Army, the Navy placed an order with Allison Engineering Co. for a liquid-cooled airplane engine of 750 horsepower in June 1930. The company designed, built, and delivered this engine to the Navy in March 1932. After completing a 50-hour development test, the Navy accepted the engine in September of that year. The Army Air Corps followed suit and soon after placed an order for the engine with the company.

Throughout the mid-1930s, Allison Engineering Co. worked to improve the engine, with the goal of making it 1,000 horsepower. After several tests and improvements to the design, the company delivered the engine to the Army Air Corps at Wright Field in Dayton, Ohio in March 1937. One month later, the V-1710 passed the 150-hour acceptance test.

By 1939, as war clouds gathered over Europe, Allison Engineering (renamed Allison Division of General Motors in January 1941) committed itself to mass production of the V-1710 aircraft engine in Speedway. At the time, Allison employed 600 people, but this number grew exponentially as orders for the V-1710 came pouring in. In April 1939, newspapers reported that the company would soon triple its facilities with construction of a new plant that would span 200,000 sq. ft. By the end of the year, employment figures had almost doubled to 1,200. Allison Division constructed additional plants in Speedway and the Indianapolis area throughout the war years and with these plants came thousands of additional employees.

Demand for the V-1710 engine made Allison Division one of the three principal manufacturers of aircraft engines in the country during the war, alongside Pratt & Whitney and Wright Aeronautical. In January 1941, Life magazine ran a feature on the engine, highlighting it as the “plane motor on which the Army puts its biggest bet.” By July 1941, the War Department awarded Allison a new contract for the engines. With this contract, total orders for Allison engines since the beginning of the defense emergency program totaled approximately $242,000,000.

America has bet heavily on the Allison engine in its aircraft defense plans, just as the war industries board in 1917 bet everything on the Liberty engine . . . the Allison engine has been delivering regularly for the R.A.F. [Royal Air Force]. Allison is now producing 400 aviation engines a month, where a year ago it was delivering only 150, and expects to approach 1,000 engines a month by the end of 1941. – “More Air Power,” Mason City [Iowa] Globe Gazette, August 13, 1941, 4.

Orders and output for the V-1710 engine continued to grow, particularly after the Japanese attack on Pearl Harbor in December 1941. By this point, employment at Allison Division surpassed 12,000. It swelled to 23,019 in October 1943. The company’s growth impacted the Town of Speedway as well. As early as 1940, Indianapolis newspapers commented on Speedway’s growing pains, reporting that officials from the town were seeking state aid to address problems that had come about from the influx of workers to the plants. These problems included the need to improve streets, sanitary conditions, and the need for a better water system. The Indianapolis Times noted that with more employees at the Allison plants came “more money, more home buying, more eating, etc.” School enrollment in the area doubled, church attendance rose greatly, and many new homes were built.

Meanwhile, Allison Division continued to impress. By March 1944, it built and delivered its 50,000th liquid-cooled engine. By the war’s end, the total figure reached 70,000. These engines powered many of the United States’ fighter planes during the war, including the P-38 Lightning, the P-39 Airacobra, and the P-40 Warhawk. The engine was also used in several fighter planes flown by the Royal Air Force of the United Kingdom.

Allison Division received high praise for the fine precision, workmanship, and durability of the V-1710. It won the Army-Navy “E” Award for excellence in production four times during the war: in October 1942, March 1944, October 1944, and June 1945. By the spring of 1945, Allison Division reduced production schedules of the V-1710 to focus more of its time on building jet engines, which could power planes at much higher speeds. The U.S Army Air Forces had awarded Allison a contract for the production of jet propulsion units in the fall of 1944. The Navy followed the Army’s lead and placed their own order with Allison in the summer of 1945, citing Allison’s “well established reputation for delivering the goods on time.” This reputation would continue through the end of the war in August 1945 and through the post-war years.

As had happened following the conclusion of World War I, racing returned to the Speedway area in 1946 to much fanfare. Left abandoned for nearly five years, the Indianapolis Motor Speedway had fallen into disrepair during World War II. Tony Hulman purchased the track in November 1945 and worked to restore it in preparation for the May 1946 500-mile race. Fans came in droves to witness the 30th running of the Indianapolis 500 that year, as racing returned to center stage in the Speedway area.

Allison’s work in Speedway and its commitment to technological advancements did not end with World War II, but rather continues through today. In addition to continuing its investment and development in the aviation industry following the war, Allison also organized a new department for the design and development of transmissions. The transmissions were manufactured for commercial and military use, with many powering tanks during the Korean War. Their production ushered in a new chapter in the company’s history. Today, James Allison’s experimental company in Speedway , now known around the globe as Allison Transmission, is one of the world’s largest manufacturers of fully automatic transmissions.

Indiana’s Daredevil Racer: Erwin “Cannon Ball” Baker and his 1914 Record-Breaking Transcontinental Motorcycle Run

On May 14, 1914, Hoosier speedster Erwin G. Baker arrived in New York City after driving over 3,000 miles across the country on his Indian motorcycle. Baker’s run from San Diego to New York City in eleven and a half days not only broke the previous transcontinental record set by Volney E. Davis in 1911, it shattered it by almost nine days (Davis’s record was 20 days, 9 hours, and 1 minute). Baker’s feat, coupled with several other speed and distance records he set during this period, quickly earned him the nickname “Cannon Ball;” a moniker he would proudly carry with him for the rest of his life.

Indianapolis Star, January 28, 1909, 8, accessed Newspapers.com

Erwin G. Baker was born in southeastern Indiana in 1882 and moved to Indianapolis with his family sometime between 1893 and 1894. In the early 1900s, he worked as a machinist in the city and performed a bag punching routine on vaudeville stages throughout the country. The act required Baker to try and keep a certain number of punching bags going at the same time. In January 1909, the Indianapolis Star lauded him as a “champion bag puncher” and noted that he was “regarded as one of the best in the country.” According to the article, Baker was preparing to compete against Harry Seeback for the national title, contending that he could keep twelve bags going at once, as opposed to Seeback’s eight.

Indianapolis News, July 13, 1909, 10, accessed Newspapers.com

While Baker may have gained some recognition for his bag punching routine, it was his interest and skill riding motorcycles that earned him early fame and jump started his career. In the summer of 1909, Baker was one of many drivers to compete at the newly opened Indianapolis Motor Speedway.

The first motorcycle races – which predated automobile races at the famous track – were held in mid-August under the sanction of the Federation of American Motorcyclists (F.A.M.). Baker competed in the ten-mile amateur championship. According to the Indianapolis Star, the event lacked a large number of entries due to racer Jake DeRosier’s recent accident on the unpaved gravel track and fear on the part of some of the drivers about being badly injured themselves. Baker, already regarded as a daredevil racer and “rider of great skill and nerve,” took home first place in the event in a time of 11:31 1-5. Just two months later, he claimed two more first place wins, one second place win, and two third place wins at a series of races in Dayton, Ohio.

Over the next few years, Baker traveled all over the country, competing in a wide variety of motorcycle races and setting many new track records.

In early 1913, the Indianapolis Star reported that he had departed on a motorcycle tour of the southern United States, as well as Cuba, Jamaica, Panama, and Mexico. The trip was said to cover some 12,000 miles. Baker was constantly testing out the limits of his Indian motorcycle and other vehicles he drove, challenging how far he could make it on a tank of gas or how long he could go without experiencing mechanical problems. Companies frequently hired him or sought his help to test and promote their brands. For instance, during Baker’s motorcycle tour of the South, he served as an experimenter for the U.S. Tire Company and tested the durability of the company’s tires over the course of his journey. Later in life, many motorsport companies would seek his endorsements as the public came to associate him with professional integrity and a sense of nostalgia for early racing.

In 1914, Baker set out to test himself once again. This time, his goal was to break the transcontinental record set by Volney Davis a few years earlier. Rather than departing from San Francisco as Davis had, Baker made San Diego his starting point. In a post card from Baker to William Waking of Waking and Company mailed May 1, 1914, he wrote:

Dear Friend Waking:

Am leaving San Diego, Cal., May 3. Will wire you just before my arrival at Richmond and ask you to assist in guiding me through your city. I’m making an effort to break transcontinental record which stands 20 days, 9 hours, one minute. Such assistance would keep me from losing time.

Yours truly,
E.G. Baker

The trek required the Hoosier speedster to travel through twelve states and across all manner of roads. In the early twentieth century, few roads were paved and the standard highway numbering system we are so accustomed to today was not yet established. While Baker often intentionally sought out demanding, primitive mountain roads or desert paths in order to prove the efficiency of the vehicle he was promoting, even the roads of his mostly flat home state of Indiana would have presented a challenge in these years. Baker also had to battle the weather in his transcontinental run, as his route took him from the scorching desert heat to colder mountain temperatures. The Indianapolis News said it best in a May 5, 1914 article, noting “the ride will not be a picnic.”

Baker was undeterred and well prepared. Newspaper accounts report that he laid out his route ahead of time, planning what roads and towns to travel through and even planting tanks of gas ahead of him in remote areas so as to avoid fuel trouble. Working with a weather expert, he also considered weather conditions for the past decade to determine what month would be best for his trip. He traveled light. According to the Indianapolis News, Baker carried two extra inner tubes, a short and long chain, a small Graflex camera, a half-gallon canteen, and a .48 caliber revolver for protection. His Indian motorcycle was a “two-speed model, equipped with electric lights and speedometer.”

Indianapolis News, May 13, 1914, 12, accessed Newspapers.com

The F.A.M. sanctioned the ride and, as a result, Baker wrote nightly reports updating the organization on his progress and offering details about his journey. Newspapers across the country also covered the story and helped track his route. The first leg of his trip, one which Baker would describe as one of the worst due to the sandy desert and high temperatures, took him from San Diego, California to Phoenix, Arizona. On May 7, the Albuquerque Journal reported that he passed through Albuquerque, New Mexico the previous afternoon and, after a short stay, continued on to Santa Fe, bringing his total mileage that day to just over 350. From Santa Fe, Baker traveled through Las Vegas, New Mexico on to La Junta, Colorado before making it into Kansas. He reached Topeka, Kansas seven days and six hours after starting his journey in San Diego and was well on his way to breaking Davis’s previous transcontinental record.

However, Baker encountered some trouble at this point in his trip. According to the Topeka Daily Capital, while road conditions in Kansas surpassed those of the desert, Baker had to contend with seven nail punctures along this leg and hit a dog that had crossed his path, causing him to topple from his motorcycle and the machine to fall. Baker injured his elbow and knee, but did not allow the incident to discourage him. He made it to Indianapolis on May 12 and even stopped for a quick dinner at home before continuing on. He had been on the road a little over nine days when he made it to his home state and had already covered 2,600 miles. It’s no wonder that the Indianapolis News referred to him as “Here-He-Comes-There-He-Goes Baker.”

Philadelphia Inquirer, May 17, 1914, 27, accessed Newspapers.com

Baker arrived in New York City on May 14, having driven well over 3,000 miles. The 11 day trip effectively shattered Volney Davis’s record by almost nine full days. The Indianapolis News rightly wrote on May 15 that the trek represented “not only the sturdy qualities of [Baker’s] machine, but the endurance of the rider.”

Reflecting on his record-breaking run in the days and weeks following, Baker credited his preparation and calculation before the trip as a large factor contributing to his success. He also praised his Indian motorcycle, noting that throughout the entire journey, which included fording streams and riding on railroad ties, he experienced no mechanical troubles. He noted that his batteries needed no recharging and that the original light bulb on the machine still burned brightly. According to Baker:

Four mountain ranges were negotiated. At one point at the northern end of Arizona, I climbed from 200 feet below sea level to an altitude of 9,647 feet into the mountain snows. It was in this mountain work that the two-speed showed its supreme qualities. My [brake] power, too, in making the precipitous descents of the winding mountain trails, never failed me for a moment. If it had I might not be able to tell this story.

Reno [Nevada] Gazette Journal, May 30, 1914, 2, accessed Newspapers.com
Baker even reported that when he arrived in Indiana, the authorities raised the speed limit for one day so he could travel through at a faster pace.

I am a Hoosier, and the welcome and encouragement my home state gave me as I passed from town to town was a generous and appreciated demonstration.

The 1914 transcontinental run was just one of numerous record-setting trips Baker would make in a variety of vehicles from the early 1900s through the early 1940s. In 1915, he set the “Three Flags record” for “touching three countries” during a run from Canada to Mexico on an Indian motorcycle.  According to the Wichita Daily Eagle, he “crashed down the Pacific Coast . . . at a speed faster than any man ever rode before on a motorcycle on any long journey.” It took him three days, nine hours, and fifteen minutes despite facing mountainous terrain and even passing through forest fires. It is not surprising that reporters christened him “Cannon Ball” Baker, as he barreled through towns and states at ever-increasing speeds. Baker died in 1960, but his legacy and contributions to motorsports continue to live on.

In the fall of 2017, the Indiana Historical Bureau will help commemorate “Cannon Ball” with a historical marker near his former home across from Garfield Park in Indianapolis. The marker celebrates the pioneer racer and test driver, while also paying tribute to his 1922 Indianapolis 500 run, in which he finished in 11th place, and his role as the first commissioner of NASCAR.
