US Navy Helicopter Crashes Off Virginia One person remains missing after a US Navy helicopter carrying five personnel crashed off the coast of Virginia. Four crew members were rescued after the MH-53E was forced to perform an emergency landing in the Atlantic about 18 miles east of Virginia Beach, the Navy said. The US Coast Guard sent two vessels to aid in the search and rescue operation for the missing crew member. Petty Officer David Weydert said ocean temperatures were 6C (42F). The four people pulled from the frigid waters were transported to hospital in Norfolk, Virginia. Their conditions were not immediately known. The Navy said the helicopter was conducting a routine training mission when it went down. The cause of the accident is under investigation. The crash is the second US military helicopter accident in as many days. Four crew members were killed when their Pave Hawk helicopter crashed in Norfolk, England, during a training mission on Tuesday. The helicopter was taking part in a low-flying exercise when it came down in Cley Next the Sea.
