San Francisco Air Crash Emergency Calls Released Emergency calls from those who witnessed the crash of a Boeing 777 at San Francisco International Airport on Saturday, and those who were aboard the plane, emerged late Wednesday, released by the California Highway Patrol, according to reports. The audio, as posted by the San Jose Mercury News, begins with a hiker who witnessed the crash. Later in the recording one woman, who gives her last name as Stone, complains that emergency vehicles had not yet arrived at the crash site. "There are no ambulances here, we have been on the ground 20 minutes," she tells a dispatcher. There are people laying on the tarmac with critical injuries, head injuries, we're almost losing a woman here, we're trying to keep her alive. The crash killed two, and seriously injured about 50 people. Its cause, and the aftermath of the crash, are under scrutiny.
