A reenactor representing Mary Henry (daughter of the first secretary of the Smithsonian, Joseph Henry), relates her experiences of June 18, 1861 at the "Mr. Lincoln's Air Force" Family Day on June 11, 2011. The event commemorated the 150th anniversary of Lowe's tethered ascent in a hot-air balloon, which attracted the support of President Lincoln and led to the creation of a balloon corps for the Union Army.
