The U.S.'s $13B aircraft carrier has a toilet problem
Given the size and complexity of such a device, and the limited number of them that are constructed (which means they are always a one-off), it would be a miracle on the order of Moses parting the Red Sea for one of them to be built __without__ such mistakes happening.<p>In you are a developer, think of the number of times you have seen a successful SAP deployment i.e. on time, on budget, meets specs. Then multiply that by about 10k to reach the complexity of an aircraft carrier.
