Yea the Tripitz had a great story during ww2. The british tried everthing from sinking with everything they had, ships, attacker planes, dive bombers, torpedo bombers, lvl bombers, SAS units, subs, and nothing would take it down until some guy made the Tallboy. I forget how many lancasters took part in the mission but each one had a tallboy, and the lancasters were flown the best night bomber group, who could get accurate hits on targets at night and day. I saw photage of the attack with the lancasters, and when those bombs fell there were splashes bigger than the ship seen from 20k and 1 or 2 tallboys hit the tripitz and just blew it up like it was just a toy. I think only 20 german sailors survived. I can't remember, but it is a great story on how the germans keep the Tripitz from being destroyed and the ways the british tried to destroy her.
