Re: Actually, there's more...
Another interesting aspect of the Vasa disaster is that they did test the ship first, and the sinking could have been avoided. Standard practice was to get a team of sailors to stand on the top deck and run from one side to the other. When they did this to the Vasa it started to rock dangerously. So obviously, the Vasa being too big to fail, the person in charge called off the test. Various people knew there was a problem, but nobody spoke up.
