<h2 id="history">History</h2> <p class="note">Further information: <a href="/facts/Airborne_observatory/WS6rV10P">Airborne observatory § Early attempts</a></p> <p>In the 19th century, <a href="/facts/Mabel_Loomis_Todd/LRceGvbW">Mabel Loomis Todd</a>, an American editor and writer, and her husband <a href="/facts/David_Peck_Todd/KBpc2Aug">David Peck Todd</a>, a professor of astronomy at <a href="/facts/Amherst_College/wuUaPkCS">Amherst College</a>, traveled around the world to view solar eclipses.<a class="footnote-ref" id="fnref:8" href="#fn:8"><sup>8</sup></a> </p> <p>In 1923, US Navy tried to observe <a href="/facts/Solar_eclipse_of_September_10%2c_1923/AMvC8y64">the solar eclipse of September 10</a> from sixteen planes, including <a href="/facts/Felixstowe_F5L/TwCgyhXc">Felixstowe F5L</a> biplane, "to determine the centerline of the eclipse from air." No photo recorded the eclipse. Officer and photographer <a href="/facts/Albert_William_Stevens/tHp7vXnA">Albert William Stevens</a> was one of the pilots on this expedition; he is sometimes called "the father of airborne astronomy".<a class="footnote-ref" id="fnref:9" href="#fn:9"><sup>9</sup></a> There was another attempt to observe a solar eclipse, this time from a dirigible. On 24 January 1925, U.S. Naval Observatory and U.S. Bureau of Standards gathered a group of astronomers to observe a <a href="/facts/Solar_eclipse_of_January_24%2c_1925/kCGv00Bx">total solar eclipse</a> from the <a href="/facts/USS_Los_Angeles_(ZR-3)/w2DHwcsf">USS <i>Los Angeles</i></a> airship over the New York City, with Captain <a href="/facts/Edwin_Taylor_Pollock/Rz5XScF6">Edwin Taylor Pollock</a> as a head of the group.<a class="footnote-ref" id="fnref:10" href="#fn:10"><sup>10</sup></a><a class="footnote-ref" id="fnref:11" href="#fn:11"><sup>11</sup></a> They used "two pairs of telescopic cameras", to capture inner and outer portions of Sun's corona, and a spectrograph. The expedition achieved good publicity, but it was not very successful in its observations - the dirigible was not very stable and the photos were blurred.<a class="footnote-ref" id="fnref:12" href="#fn:12"><sup>12</sup></a> The next attempt was successful: an expedition of the <a href="/facts/Naval_Observatory/81pxwM2R">Naval Observatory</a> to observe the <a href="/facts/Solar_eclipse_of_April_28%2c_1930/Fw8j7BeT">solar eclipse of April 28, 1930</a> on <a href="/facts/Honey_Lake/81jYnnfs">Honey Lake</a>, California, with <a href="/facts/Vought_O2U_Corsair/PlcbqQWY">Vought 02U-1</a> plane equipped with a camera, recorded "the approach of the shadow".<a class="footnote-ref" id="fnref:13" href="#fn:13"><sup>13</sup></a> </p><p><a href="/facts/United_States_Army_Air_Corps/f5FK5BKQ">Army Air Corps</a> and the <a href="/facts/National_Geographic/vnuhsmYg">National Geographic</a> Society organized another expedition in 1932, to observe <a href="/facts/Solar_eclipse_of_August_31%2c_1932/4yaoA9zD">the eclipse of August 31</a>. Accompanied by Lieutenant Charles D. McAllister of the <a href="/facts/United_States_Army_Air_Corps/f5FK5BKQ">Army Air Corps</a>, Stevens took the first photograph of the Moon's shadow projected onto the Earth during a <a href="/facts/Solar_eclipse/2XsCFG1a">solar eclipse</a>.<a class="footnote-ref" id="fnref:14" href="#fn:14"><sup>14</sup></a><a class="footnote-ref" id="fnref:15" href="#fn:15"><sup>15</sup></a><a class="footnote-ref" id="fnref:16" href="#fn:16"><sup>16</sup></a> </p><p><a href="/facts/Royal_Canadian_Air_Force/RcKdhuC3">Royal Canadian Air Force</a> observed the <a href="/facts/Solar_eclipse_of_July_9%2c_1945/38r59yRE">solar eclipse of July 9, 1945</a> from four planes: "a Spitfire, a Mitchell, and two Ansons"; three planes used seven standard aerial photography cameras, "adjusted to automatically take exposures".<a class="footnote-ref" id="fnref:17" href="#fn:17"><sup>17</sup></a> For the <a href="/facts/Solar_eclipse_of_May_9%2c_1948/cUNDw8Xz">solar eclipse of May 9, 1948</a>, National Geographic society organized several ground stations and two backup planes for a case of bad weather. Two <a href="/facts/B-29/79pXKprr">B-29s</a>, stationed on the <a href="/facts/Aleutian_Islands/HDnCEHMu">Aleutian Islands</a>, successfully observed and photographed the eclipse.<a class="footnote-ref" id="fnref:18" href="#fn:18"><sup>18</sup></a> </p><p>For the <a href="/facts/Solar_eclipse_of_June_30%2c_1954/P7EuWfsW">solar eclipse of June 30, 1954</a>, observations were made "from the open door of a special Lincoln aircraft". Photographs helped "to derive coronal brightness and polarization, along with sky brightness and polarization". Several missions were made in 1960s. Three <a href="/facts/NC-135/IN2jTSGU">NC-135</a> planes of the <a href="/facts/Los_Alamos_Scientific_Laboratory/tlrLkV7r">Los Alamos Scientific Laboratory</a> (LASL) were used for eclipses observations from 1965 to 1980. The planes were operated by the <a href="/facts/United_States_Atomic_Energy_Commission/7VXrvVJ9">Atomic Energy Commission</a>.<a class="footnote-ref" id="fnref:19" href="#fn:19"><sup>19</sup></a> </p> <p>In <a href="/facts/1973_Eclipse_Flight_of_Concorde_001/KF6UEqh6">1973, the French Concorde prototype, c/n 001</a>, was modified with roof-top portholes for a <a href="/facts/Solar_eclipse/2XsCFG1a">solar eclipse</a> observation mission of <a href="/facts/Solar_eclipse_of_June_30%2c_1973/FSTGV5r7">30 June 1973</a>, at the end of the French testing programme.
