Much has been made of the 100th anniversary of the sinking of the Titanic, but few have had the chance to dive to the wreck since its discovery in 1985. One man that has is Dave Christensen. In 2005, he was able to take part in a 12 hour dive to the ship. The New Hampshire resident is a partner in Clear Path Entertainment, a company that books entertainment acts and also works to bring historical collections to venues around the country. He has been the media director on Titanic expeditions, and he has worked with RR Auction in Amherst as a TITANIC expert for their upcoming auction of a vast collection of items from the wreck.
