It is not well-known to people who don't spend a lot of time on aircraft carriers that the bridge is always on the starboard (right) side. The reason for this is that incoming pilots have a nearly universal tendency to veer left in emergencies. If the bridge were to be located on the left, known as the "port" side in nautical cant, the risk for accidents would increase.
How do we know? Because there have been only two aircraft carriers with bridges on the portside. One of those ships was the Japanese vessel Hiryu. It became known for its many landing-related accidents in WWII.
The Hiryu had some impressive statistics to its name. It displaced 17,300 tons of water, was 746 feet long, and could travel at 34 knots. Its flaw, though, was a serious problem and helped prove that the bridge should not be on the portside.
