SAN FRANCISCO — Coast Guard search-and-rescue teams on Wednesday resumed the hunt for missing Microsoft researcher Jim Gray, who vanished while sailing alone outside of the Golden Gate Sunday.
Gray, 63, an ACM Turing Award winner and an acknowledged expert in database systems, hasn't been seen since he sailed his 40-foot, red-hulled boat, Tenacious, west of here, intent on scattering his mother's ashes near the Farallon Islands. Weather conditions have been good around San Francisco.
Coast Guard officials said Tuesday they had received reports of a red-hulled boat near Stinson Beach, north of the Golden Gate Bridge. No boat was sighted. While Gray is considered an experienced sailor, his daughter said he often left safety gear at home.
The Coast Guard has been using C-130 fixed-wing aircraft, HH-65 Dolphin helicopters, and a number of patrol boats in a search that has covered nearly 16,000 square miles.
Gray's disappearance is another shock to the Bay Area technology community. In late November, CNET technology editor James Kim and his family got lost driving in the Oregon mountains. Kim's wife and two daughters were rescued, but Kim, who had left on foot to find help, was found dead.
Gray joined Microsoft 10 years ago, after working as an industrial researcher and software designer at IBM and Tandem. He won the ACM Turing Award in 1998 for his work on transaction processing.
He is widely heralded as one of computing's leading lights. He discussed computing and storage trends in a 2003 interview with another computing wizard, David Patterson of U.C. Berkeley.
