Military and history buffs will be able to watch online Saturday as the remaining Doolittle's Raiders drink a final toast to comrades who died during or after their World War II bombing attack on Japan. The ceremony being held at the National Museum of the U.S. Air Force near Dayton will be streamed on the Air Force's website. Four of the 80 Raiders are still alive, and one of them might not be able to attend because of health problems. They have traditionally offered the toast with specially engraved goblets in a private ceremony during annual reunions.
