    <title type="html"><![CDATA[The 509th Composite Group at Wendover Air Force Base<br />
]]></title>
    <summary type="html"><![CDATA[<p><strong><em>In the words of historian Roger D. Launius, “America in the early 1940s was a nation on the move as never before. The exigencies of war reoriented virtually every aspect of the culture, economy, demographics, and politics of aviation in the United States.” The 509th Composite Group at Wendover Air Force Base played an integral role in this transformation by training new pilots, testing new aviation technologies, and successfully executing the Manhattan Project, bringing an end to the bloodiest war the world has ever seen.</em></strong></p><img src="https://www.intermountainhistories.org/files/fullsize/670f71176dece6eb09d290a00396650a.jpg" alt="[Untitled]" /><br/><p><span style="font-weight:400;">One of Utah’s most significant contributions to the American effort during WWII was the creation and training of the 509th Composite Group, “the only unit ever to drop an atomic bomb in combat.” Originally the 393rd Bombardment Squadron, the 509th was created by General Henry “Hap” Arnold, who selected Lt. Colonel Paul W. Tibbets to head the group. Lt. Col Tibbets was given the options of Mountain Home, ID; Fairmont, NE; and Wendover, UT to host his group, as “all three had acceptable facilities and runways for B-29 operations.” Lt. Col Tibbets ultimately chose the site in Utah based on its extensive bombing and gunnery range facilities, as well as the history of heavy bomber training in Utah. The required facilities were already in place in Wendover. The Utah site was also desirable because of its relative proximity to Los Alamos, NM; the site responsible for developing the nuclear payload Tibbets’ team would be delivering. Additionally, since Wendover was so isolated, the project could be kept secret from prying eyes, both foreign and domestic.  </span>
<span style="font-weight:400;">The 509th Composite Group trained from 1944-1945, dropping 5,000 to 10,000 pound dummy bombs, conducting rapid turns to avoid the nuclear blowback (though the crews weren’t told the reason for these maneuvers), and increasing accuracy to within 200 meters of their targets. On May 29, 1945 the group was relocated to Tinian in the Mariana Island chain. Afew months later they dropped two atomic bombs on Japan, effectively ending the world’s largest and bloodiest conflict. From the “History of the 509th Composite Group” written in 1945, there was an interview with Lt. Colonel Tibbets where he was asked about the success and contributions of the 509th Composite Group. When asked whether the group “measured up to expectations” regarding its contributions and fulfillment of the Manhattan Project, Lt. Colonel Tibbets replied:  </span>
<span style="font-weight:400;">The mission of the 509th was accomplished. Its success is now a matter of world history. In all probability this success surpasses the expectations of those intimately connected with the early phases of the project. It is safe to say that the 509th never held up the work of the project. Many times the 509th caused the project to speed up their efforts because the unit shaped up faster than expected and was committed to the theater ahead of schedule. The success of this organization is due to teamwork by all people in the outfit and the willingness with which they cooperated with the project people to accomplish our assigned mission.</span>
<span style="font-weight:400;">Following the successful conclusion of World War II, thanks in large part to the efforts of the 509th Composite Group, Wendover Air Force Base continued to train new generations of pilots, develop new technologies, and build the fledgling Army Air Corps into the most dominant Air Force the world has ever seen.  </span></p><p><em><strong><a href="https://www.intermountainhistories.org/items/show/794">For more (including 4 images) view the original article</a></strong></em></p>]]></summary>

    <title type="html"><![CDATA[Independence Day and Wendover Air Force Base, Utah<br />
]]></title>
    <summary type="html"><![CDATA[<p><strong><em>Wendover Air Force Base is situated on the Nevada-Utah border. It currently functions as an airport and featured in the film Independence Day.</em></strong></p><img src="https://www.intermountainhistories.org/files/fullsize/4417e6fb87ba2e9c0042ff9510ce4c4e.jpg" alt="Wendover AFB – Hanger" /><br/><p>Wendover Air Force Base, currently Wendover Airport, is in Tooele County, Utah, on the Nevada-Utah border. Constructed in 1940 by the Army Air Corps, the airbase was used by both the Air Corps and its successor, the U.S. Air Force, until 1965. While it was in operation, bomber crews trained at the base, including the teams that carried the 1945 atomic bombs dropped on Hiroshima and Nagasaki.</p><p>The base features heavily in Roland Emmerich’s 1996 science fiction blockbuster Independence Day. It is used in the film to depict both Area 51 and El Toro airbase. The film begins with massive flying saucers appearing above major cities. David Levinson, played by Jeff Goldblum, realizes that the ships are broadcasting a countdown, at the end of which each ship destroys the city beneath it. As the counter attacks against the aliens fail, survivors begin to regroup at Area 51, where the U.S. government has been studying alien life for years. After an alien escapes and is killed, Levinson discovers a way to disable the shields that prevent the alien motherships from being harmed. Levinson and Captain Hiller, played by Will Smith, are successful in sabotaging the ship, allowing the survivors to mount a successful counter attack and alert other resistance groups of how to defeat the aliens.</p><p>The airbase is used throughout the film as two separate locations:  El Toro and Area 51. The airbase features extensively as both a staging ground for the military’s offensive operations and as a haven for refugees fleeing the alien invasion. During both the alien attack scenes on the refugees at Area 51 and the military at El Toro, the airbase was used as the location for action set pieces involving multiple explosions. As El Toro air base, Wendover is used to represent the military’s presence throughout the film and the Air Force’s attempts to combat the alien threat. As Area 51, Wendover air base is used to highlight both the infamous military installation but also the alien conspiracies and urban myths that are famous in the region. It is the site of the film’s most iconic scene: Bill Pullman’s President Thomas Whitmore’s Independence Day speech to the pilots and volunteers prior to the attack on the nearby spaceship. Since becoming an airport, the site has been used for multiple other films, including 2003’s Hulk.</p><p><em><strong><a href="https://www.intermountainhistories.org/items/show/231">For more (including 3 images) view the original article</a></strong></em></p>]]></summary>

    <title type="html"><![CDATA[Wendover Air Force Base]]></title>
    <summary type="html"><![CDATA[<p><strong><em>Wendover Air Force Base has a short, but rich history. It is responsible for the training of thousands of airplane pilots and bomb testings, including the fighter division that dropped the first atomic bomb in world history.</em></strong></p><img src="https://www.intermountainhistories.org/files/fullsize/76dc54ef567061c7fc9076443908fe68.jpg" alt="Wendover Air Field during World War II" /><br/><p>Created before the U.S. entry in World War II, Wendover Air Force Base [AFB] originally began as a small field in Wendover, Utah. Located on the Utah-Nevada border, the town had a population of only 103 people at the time. In 1941, newly acquired lands increased the base size to make it the largest bombing and gun range in the world at that time. The land was acquired despite the protests of local ranchers and farmers who claimed that it would be detrimental to their income. Wendover AFB’s purpose in WWII was that of a bombing and gun range, testing site, and research center for aircraft warfare. Some of the unique specialties included at Wendover AFB included remote controlled missiles and airplanes, but the main focus was on heavy bombing groups of B-17s and B-24s. Many bombing groups completed their training at the base, including some that flew in D-day and other worldwide operations. Three of the pilots that trained here later earned Medals of Honor for their military service. Wendover AFB also played a part in the preparation to drop the atomic bombs on Japan. Col. Paul W. Tibbets, who led the 509th composite group, chose Wendover for its size and isolation, both necessary for the security of the project. As the project came closer to fruition, the “Little Boy” bomb was assembled and tested at Wendover. After the conclusion of WWII, the use of the wartime air force bases around the nation was reduced. The case was the same for Wendover. Use by the Air Force ceased entirely after 1986, and now the base is used as a museum showcasing the base’s history.</p><p><em><strong><a href="https://www.intermountainhistories.org/items/show/42">For more (including 3 images) view the original article</a></strong></em></p>]]></summary>
