Perhaps the sub implosion was all part of the 'fully immersive Titanic experience'? I can't even get into a lift, honestly, I walk up 10 flights of stairs rather than get into an enclosed box. What's the point of going down to the sea bed to look at wrecks anyway? It's downright creepy. You can see anything on TV these days, but some people just have a taste for extremes, probably the £250K price tag made it feel super exclusive, therefore it must be 'the ultimate' something or other.
