One of the most common questions we get about our submarine, Antipodes, is this: how long can you survive in case of an emergency?
As with most submarines, especially those with similar A+1 safety classifications from the American Bureau of Shipping, the answer is 72 hours, or roughly 3 days. (Actually, the technically correct answer is 360 man-hours, so 72 hours is at our full complement of 5 people.) Of course, it is difficult for me to imagine what it would be like to be trapped in a small submersible with four other people for three days ... the whole time waiting to be rescued.
In 1973, two submarine pilots had the misfortune of living through this exact experience. At the end of an exhausting 9-hour mission 150 miles off the coast of Cork, Ireland, the Pisces III submarine became disabled and sank to the ocean floor at 480 meters (1,575 feet), trapping pilots Roger Chapman and Roger Mallinson with no way out. They waited on the sea bottom for over 3 days while a massive global rescue effort took place with the entire world watching and holding its collective breath. Much like the Apollo 13 mission three years prior, it was a life-and-death struggle where hundreds of professionals worked feverishly to bring home safely two brave men from an immensely hostile environment. The outcome was a testament to the courage of the trapped pilots, but an even stronger affirmation of the ingenuity, resolve, and teamwork of the many people who made possible the successful recovery of the sub and crew.
Chapman later wrote a gripping book about the ordeal, and he appropriately entitled it No Time On Our Side. I think about this story every time I get in our sub, and I have made it required reading for all of our pilots and crew. I hope that someday someone will turn this into a major motion picture and associated documentary, because it is a dramatic human story that should be shared with a global audience and new generation of explorers.
