OK, so really a 'wreck' per se, but you just gotta love these pictures of the USS Cole being retrieved at sea by this Norwegian vessel! The music's pants, but check out the pcitures! A serious feat of maritme engineering.

You may remember that she was hit by a water-borne suicide attack by the Al-Q boys whilst being alongside in port in Aden a coupla years back.

<font color='#0000FF'>Amzing how they have a ship to do a piggy back.
When in the Azores there was a huge Russian Tug that the locals call the 'Vulture'. The Tug is one of the 3 largest in the world and all it does it hangs around the Azores until they get a distress call from a ship in the Atlantic. They charge half of the value of cargo for their fees. Where was it during the Prestige saga I don't know, doubt they were even called out.

<font color='#000080'>The do the same thing with the top bit of an oil rig. A few years ago they moved the biggest thing ever- the Aker Troll rig out of Stord, near Stavanger, Norway. It had concrete legs that weighed a million tonnes that they towed out to sea then flooded so they are just at sea level.  Then they float in the topsides, place them above the legs and pump air into the legs to lift the whole thing out of the water.

The rig doesn't look too big from a distance until you realise that the white box on one end of it is an 8 storey building.

If you really want to see something impressive, the cranes that lift the topsides up are something else.
