General Emmett E. "Rosie" O'Donnell Jr. was a United States Air Force four-star general who served as Commander in Chief, Pacific Air Forces (CINCPACAF) from 1959 to 1963. He also led the first B-29 Superfortress attack against Tokyo during World War II.

The Boeing B-29 Superfortress is an American four-engined propeller-driven heavy bomber, designed by Boeing and flown primarily by the United States during World War II and the Korean War. Named in allusion to its predecessor, the B-17 Flying Fortress, the Superfortress was designed for high-altitude strategic bombing, but also excelled in low-altitude night incendiary bombing, and in dropping naval mines to blockade Japan. B-29s dropped the atomic bombs on Hiroshima and Nagasaki, the only aircraft ever to drop nuclear weapons in combat.
