This episode of "Building San Francisco" looks at the history of elevator technology. We learn of its early use for freight before elevators were safe for passengers; the first passenger elevators which had operators; current elevator technology; and Destination elevators-the latest high tech way to ride to the top! It features a ride on an elevator installed in 1913 and a look at its tiny machine room; a ride on the famous St Francis Hotel outside elevators with breathtaking views of the CIty; a tour of its machine room; a ride on a Destination Elevator with no buttons inside the cab; and a revealing tour of a brand new digital machine room.
