disaster free for 16 point something hours. that's what it would take for this thing to pass minimal standards, 16.4 hours. that's it. that's as long as it would have to run without something really bad happening. something like what's been happening, which is the thing leaking or driving itself off course inexplicablly. even if it didn't break down, even if it worked as directed, it doesn't work. it is the printer, copier, scanner, fax that cannot print, cope, scan or fax problem. in order to swim, it needs to have a flat bottom. this is not a catamaran, it is a tank. having a flat-bottom boat is the thing we stopped allowing because you really, really need them to have a v-shaped hull because the v-shaped hull makes the vehicle capable of protecting the people inside it from things exploding outside of it when it is driving around.
