U.S. military leaders are among thousands who have joined in a tribute to World War II's Doolittle Raiders, the World War II airmen whose daring bombing attack on Japan helped boost American morale.
A flyover by five B-25 bombers helped cap a Saturday memorial service in which a wreath was placed at the Doolittle Raider monument outside the National Museum of the U.S. Air Force near Dayton in southwest Ohio.
Three of the four surviving Raiders plan a final ceremonial toast to fallen comrades Saturday evening. The fourth couldn't travel because of health issues.
Commander James "Jimmy" Doolittle commanded the daring mission credited with throwing the Japanese off balance after a string of military successes.
