97-Year-Old Man Lands Rare Bomber Retired Lt. Col. Richard Cole, 97, made history when he landed a rare B-25 bomber this week at a Florida reunion of World War II veterans. There are only four veterans alive who flew the April 18, 1942 "Doolittle Raid" on Japan after Pearl Harbor. For their reunion, which they say will be their last, the vets plan to toast with a bottle of Cognac from 1896, the year Cmdr. James Doolittle was born.

'Superman' Turns 75 It's a bird, it's a plane, it's the 75th anniversary of "Superman and Lois Lane." The comic, created by Cleveland natives Jerry Siegel and Joe Shuster, first appeared 75 years ago for only 10 cents. The cover of the April 18 issue, which now goes for more than $2 million, showed Superman lifting a car over his head. The brawny character changed over the years, beefing up and going on TV with George Reeves and to movies with Chris Reeve. "The Man of Steel" will be the star of a new "Superman" film due in June. Back in 1938, DC Comics acquired the rights to Superman from the authors for $412.

Three New Planets Discovered There is good news in the stars tonight. Combing through more than 15,000 solar systems, scientists have found three new planets around one sun. Each is a little bigger than Earth and, in theory, could sustain life. They're what scientists call "Goldilocks Planets" because they're not too hot and not too cold. The bad news is that they're more than 1,000 light years away. One light is about 6 trillion miles!
