Hello; Worth an honorable mention: the Hubble space telescope was initially unusable because of an error by a technician during the construction of the interferometer, causing the mirror to be off by a fraction of the width of a human hair. It cost a total of $700M to repair. At 4:06 - In regards to 3, I'd say that France, Spain and Portugal had it coming. They could have greatly minimized the what turned out to be a major oil spill, by allowing them to temporarily dock in their ports, to Patch Up the Ship. However, they were clearly thinking of the short-term issues of allowing them to dock, when they should have been considering the long-term issues, caused by a major oil spill, which ultimately resulted from their refusals. Sure, one could blame the captain for refusing to distance himself from the coastline. Then again, he was probably refusing to distance his ship from the coastline, in spite, likely as a result of the refusal to allow his ship to dock. Truthfully, anyone in that same position probably would have done the same exact thing.
