A Spokane-based airman and nine other U.S. service members died when a pair of Marine Corps helicopters crashed off the coast of Africa, U.S. military officials confirmed Sunday. Senior Airman Alecia S. Good, 23, of Fairchild Air Force Base was on board one of two CH-53E choppers carrying a dozen crew and troops from a U.S. counterterrorism force that went down during a training flight Friday in the Gulf of Aden, near the northern coastal town of Ras Siyyan in Djibouti.
