On Friday the 13th of December 1935, Major Ladd was piloting
Boeing P-12F,
32-100, c/n 1676, '60', the 24th of 25 of the model built, of the
36th Pursuit Squadron, from Langley Field to
Miami, Florida, for the eighth annual All American air maneuvers, an air race and exhibition held 13–15 December. He had departed Langley on Thursday morning, 12 December, and had spent the night at
Fort Bragg, North Carolina, apparently due to adverse weather. At ~1400 hrs. EST, the biplane fighter crashed into a swamp near the
Wimbee River on
Heyward Island, ~3 miles E of
Dale, South Carolina, in
Beaufort County. A front page news item in
The State,
Columbia, South Carolina, the next day, observed that the plane's two machine guns were badly broken. "Major Ladd's body was badly mangled. Authorities from
Parris Island removed the body about 5:30 o'clock this afternoon and carried it to Parris Island to await instructions. Major Ladd appeared to be between 40 and 55 years of age." (He was 45.) "Parris Island officers who visited the scene said they could not tell what caused the crash; neither did they know what Major Ladd's destination was, nor where he had come from. The orders he flew under were sealed, as is customary." No funeral arrangements had been made by Friday night, 13 December. Ladd was survived by his parents, of
Sherman, Texas, his widow, and a daughter, Miss Billie Ladd. ==Commemoration==
