Boeing once took a 757 to Lhasa, Tibet, to demonstrate just this
capability. Lhasa is one of the highest airports in the world (maybe
the highest. Does anybody know? La Paz?) and it is surrounded by
mountains. The 757 was accelerated to V1, one engine was killed, and
the takeoff was continued. The airplane circled and landed without

Boeing made a promotional tape of this event and anyone who has a
chance should see it. Video was filmed from inside the cockpit and you
can see the mountains all around. The ground proximity alarm (terrain!
terrain!,,,) could be heard almost continuously. Scary.
