Scotty beamed up

He's Dead Jim. James Doohan -- Star Trek's immortal engineer Scotty -- entered the undiscovered country this morning, succumbing to pneumonia and Alzheimer's disease (aka "transporter dementia"). In other words, his lungs and brain had had all they could take and they couldn'a taken any more. I suppose it's too much to ask that he'll be discovered trapped in a transporter feedback loop 75 years from now -- he's dead already.
