(CNN) – When pitcher Mariano Rivera stepped off the mound for the final time last season, he became the last professional baseball player ever to regularly wear the number 42.
That's the only number retired across all of Major League Baseball, because Jackie Robinson owns that one, now and forever.
It was exactly 67 years ago today that Robinson became the first African-American to break baseball's color line by suiting up for the Brooklyn Dodgers.
His contract paved the way for so many players that would follow like Willie Mays and Hank Aaron.
And it's why today, all of baseball honors this civil rights pioneer by donning his number.
Happy anniversary to one of my heroes.
(CNN) – The Bluefin-21, an autonomous underwater vehicle, is back in the water searching for missing Malaysia Airlines Flight 370. But some experts say other AUVs could, and should, be deployed.
CNN analysts Rob McCallum, an ocean search specialist, and David Soucie, author of "Why Planes Crash," discuss.
(CNN) – The U.S. Navy's Bluefin-21 is the object on which all hopes of finding Malaysia Airlines Flight 370 are currently pinned.
It is only about 16-feet long. It must map a section of the ocean about 230 square miles big. Imagine the city of Chicago hidden deep under water, that's the size of the area the unmanned underwater vehicle must now search.
The company that created it tells CNN that the Bluefin-21 is back in the water, on what is now the 40th day since the plane disappeared.
This is the second time the team is sending down the sub. They had to make adjustments because as CNN aviation correspondent René Marsh reports, the first dive came to an abrupt and unexpected end.
(CNN) – The Bluefin-21, an unmanned underwater vehicle, is back in the water searching for Malaysia Airlines Flight 370. But considering the ocean depth and the size of the search zone, is the Bluefin the right equipment?
U.S. Navy Deputy Director for Salvage and Diving Mike Dean says there is at least one other piece of technology, the Orion, that could contribute more to this search.
