DAYTON, Ohio -- World War II era bomber planes have rumbled over Ohio to begin events marking the 75th anniversary of an attack on Japan known as the Doolittle Tokyo Raiders' attack.

The B-25 bombers that flew in Monday are on display at the National Museum of the U.S. Air Force near Dayton. The museum says 11 landed Monday and will take part in a flyover at Tuesday's memorial service.

Retired Lt. Col. Richard "Dick" Cole is the last alive of the original 80 Raiders. The 101-year-old Dayton area native plans to take part in the anniversary events, returning to Ohio from his Comfort, Texas, home.

Two B-1 bombers from the 34th and 37th bomb squadrons at Ellsworth Air Force Base, South Dakota, are to fly over at the end.
