The USS Nevada was in a really tight spot but managed through the debris of sunken ships, fires, bombs, oil, gas, you name it.
At Pearl Harbor, most of the ships were caught at anchor and the navigation channel was clear. USS Nevada was also far more maneuverable than any barge.
WWL is now relaying that the rescue forces need even smaller boats. Small powerboats, jetskis and such. They are needing to get into smaller areas than the airboats and such can get into. Also, any sealift people can provide would be appreciated.
WWL also reports that the heavy lift choppers they are using to drop bags in the levee gap can only make one drop then have to RTB for fuel. There are no forward operating bases in the city with fuel yet.
