Sunday marked the 84th anniversary of the Pearl Harbor bombing — a shocking attack that killed 24-hundred Americans, including more than 11,000 aboard the USS Arizona.

The USS Arizona was the flagship of Battleship Division One. She sank after her forward magazines exploded after being hit by a bomb.

The US Navy, in coordination with the Pearl Harbor National Memorial, removed significant portions of two World War II-era mooring platforms from the USS Arizona in October to help preserve the historic ship.

Sunday is Pearl Harbor Remembrance Day, marking nearly 85 years since the USS Arizona was sunk, on a day that President Franklin D. Roosevelt said would “live in infamy.” And, it turns out, the ship has been leaking oil since that time.

Operation 85, a family advocacy group, has worked tirelessly the past two years to obtain the DNA of 643 descendents of those onboard the USS Arizona.

Virgin Galactic’s mothership, EVE, completed its inaugural flight from Spaceport America in New Mexico to Mesa Gateway Airport in November. Police responded to the area for reports of a man with a gun. As they searched the neighborhood, one of the officers at the scene found the suspect.
