A group of divers is bidding to turn the old aircraft carrier in to a dive wreck. Michael Byfield and James Doddrell believe turning the former Portsmouth-based ship into a reef could bring £40m into the Devon economy, creating the largest artificial shipwreck reef in Europe. It could repeat the success of HMS Scylla, which attracts thousands of divers to Plymouth, generating millions of pounds for the local economy. They say they do not want to see the former flagship follow in the wake of HMS Invincible, which was towed to Turkey for scrap. They would like to get it ready in time for the closing ceremony of the 2012 Olympics.
