(We Just Found A) Yellow Submarine

The BBC reports on local Scottish fishermen who found a Royal Navy mine-hunting mini-sub drifting in the waters of the Mull of Oa. The article details what happened when the men contacted the Navy about their find:

"Mr Hastie, who is a member of the local coastguard, contacted his colleagues at Clyde Coastguard to explain what had been found.
"They passed the details on to the Faslane Naval Base, but were initially told that no submarines were missing.
"The navy later admitted that one of its vessels was missing.
"However, Mr Hastie said the navy had not been in touch with either of the two men to thank them for what they had done.
"You would think they would have phoned up and thanked us because it is quite an expensive piece of kit to leave lying about. "

Some information on these mini-subs (Remote Controlled Mine Disposal Vehicles, or RCMDVs)can be found here.
