A small plane crashed in East Palo Alto, around 30 miles south of San Francisco, Wednesday morning after hitting an electrical transmission tower. All three people on board, who were Tesla employees, were killed, and four homes in the residential neighborhood were damaged. Flying through thick fog shortly before 8 a.m., the twin-engine Cessna hit the tower and fell on to houses and vehicles below in several pieces. The crash cut off power to 28,000 people in the city of Palo Alto, including Stanford Hospital, which had to operate on backup power. No one on the ground was hurt.
