Jeff Smith of the San Diego Reader just finished a two part article on the 1947 job that Belyea Truck company did in moving of Palomar's 200-inch mirror from Caltech to Palomar Mountain.
Check out Part 1: Odyssey of the Giant Eye and Part 2: The Giant Eye Rolls Uphill by clicking on the links.
Spoiler Alert: The mirror made it safely to Palomar. Even so, the articles are a good read.
Below is a picture taken just outside the dome of the 200-inch telescope just after the mirror arrived on site. Lead driver Lloyd Green can be seen shaking hands with owner Jack Belyea. The trailer with the mirror crate is behind them.
