Also from the Wikipedia entry: "Tubby, a black male cocker spaniel dog, was the only fatality of the Tacoma Narrows Bridge disaster. Leonard Coatsworth, a Tacoma News Tribune photographer, was driving with the dog over the bridge when it started to vibrate violently. Coatsworth was forced to flee his car, leaving Tubby behind. Professor Farquharson and a news photographer attempted to rescue Tubby, but the dog was too terrified to leave the car and bit one of the rescuers. Tubby died when the bridge fell, and neither his body nor the car were ever recovered."
From the Wikipedia article: "Elliot's original films of the construction and collapse of the bridge were shot on 16mm Kodachrome film, but most copies in circulation are in black and white because newsreels of the day copied the film onto 35mm black and white stock."
It took me a while to understand this principle, but once I did, it made total sense. As long as your performance is good, you'll keep getting promoted. It's only when your performance is bad that they'll stop promoting you. So you get promoted to your level of incompetence.
How the times have changed.
