At 25, SARSAT To Be Replaced by GPS, Glonass

WASHINGTON
�- The development of Search and Rescue Satellite-aided Tracking (SARSAT) is commonly traced to October 1972, when a plane carrying U.S. Reps. Hale Boggs of Louisiana and Nick Begich of Alaska disappeared during a campaign trip while flying from Anchorage to Juneau. If their aircraft only had been equipped with a beacon capable of emitting a signal to a satellite, rescuers might have at least located the wreckage, if not actually found survivors at the site. It did not. Boggs and Begich were never found.
