One team diving, the other drilling.

This is a job for the Thunderbirds!

Well this article is 5 years old, so apperantly neither of them found anything.

A telegram was found which read: 'Amber Room operation complete, object stored in B.Sch. W.V'.

If that telegram was supposedly dating from the war, it's incredibly unusual that such an operation wasn't given a code name. Sounds to me like there's some fakery at work there. And let us assume it IS a genuine message back to HQ informing them of a job well done, why would they need to inform their superiors of the location? Surely they'd be fully aware of this information as it was they who decided where the stash was gonna be hidden in the first place. Military communications about secretive operations don't even contain a fraction of the info about the operation that the one line telegram did.

What you have to take into account is that a lot of these treasure hunting expeditions are financially backed by large consortiums, who only keep the money flowing whilst there is, at the very least, some minor form of evidence that the hunters they've subscribed to are on the right trail. Such a telegram would be the perfect device in such a scenario, especially if the backers were beginning to have doubts about carrying on funding the expedition.
