Waste is right, just goes to show the government has "money to burn"!
I suppose they NEEDED to use running motors but being as there is quite a bit of flammable stuff on a outboard motor I think engines that didn't run would give them the same effect...
Look to probably see that boat on some government auction site...
Think the Yanks ,have a thing about targeting RIBs
I was the target boat for the unmanned "Protector" test series here in San Diego.
They told me that light was just the FLIR !
Wondered what that burning smell was
