A superyacht called 'Octopus' – Octopus, the 414 foot megayacht owned by Paul Allen, the co-founder of Microsoft, was moored in Canary Wharf during the London 2012 Olympic Games. A combination of the boat being in the right place at the right time has allowed its inclusion in the recovery efforts.
Not your usual recovery vessel – David Mearns is heading up the recovery expedition. He told CNN: "I don't think we'd be able to do it now if it weren't for Paul Allen's interest... There are only a handful of people or companies in the world that would have an interest, the capability and the passion to do this."
