Well done dozy idiots

Well done to the team of Dutch computer wizards who spent ages computer modeling San Fransisco bay to test the theory that 3 convicts may have escaped from Alcatraz in 1962 in a home made rubber boat. Of course if they'd bothered to check they could have saved themselves weeks of work, Mythbusters did it themselves in 2003, using exactly the same materials, and made the shore safely.
Sometimes all you gotta do is check!
