US explorer and counter-terrorism operative Scott Cassell has seen his homemade submarine make its maiden dive. His 1.5 ton vessel - named The Great White - launched off the coast of Tioman Island in Malaysia. Scott had spent years creating the sub out of mostly recycled materials after finding a rusting steel hull discarded in a California back garden. Along with close friend Scott Read, an engineer, he meticulously made it sea worthy - equipping it with three external cameras, an observation bubble and adapting it to run on electricity.
