the submarine hit a mountain because it is not on their map!
To quote the article:
"Military officials have said that the submarine's main chart was prepared in 1989 and did not show any potential hazards within three miles of the crash site. Satellite images taken since then show the wedge-shaped outline of the undersea mountain. But officials have said the agency that prepared the charts had never had the resources to use the satellite data to improve them.
Also yesterday, Kent D. Lee, the chief executive of East View Cartographic Inc., a map company based in Minneapolis, said Russian Navy charts indicate more hazards in that part of the ocean than were on the American charts, though they also fail to show the undersea mountain.
Mr. Lee said the Russian charts have been available for five years. He said one of the Russian charts noted that the area where the crash occurred had been "insufficiently surveyed." It also warned: "Cautionary measures should be taken when sailing.""
so US has the technology but failed to take advantage of it. Now the FBI or CIA has some more things to do.
