OK this is getting out of hand! Of course. To believe in a "Conspiracy Theory" you are saying that White Star killed all those who drown. White Star was not planning on killing its employees or clientele. That would bring some ill will on behalf of several people had that been that actual plan. Since the Olympic class liners were very safe ships, they had anticipated that Olympic would deliberately ram and iceberg, and take so long to sink that all passengers would be able to be ferried away safely! There was no reasonable explaination why the White Star would spend so much money to switch over the identies of each ship. The cost of switching the keel numbers to match the keel numbers on the propellers, switching out all the embroyied linen, stationary, ashtray, dishes and so on would be time consuming and cost prohibiting. The "Conspiracy Theory" is just a foolish waste of time and a slur on the employees that would have taken part on a hoax where lives where lost. You might as well join the ranks of the Hangar #18 in Roswell or the man hiding on the grassy knoll taking a shoot at JFK. It wastes fruitful time of ppl to try to make that streach. Besides a parting question, if they did switch the Titanic with the Olympic and the Olympic sank, the remaining ship was in September 1937 sold to Sir John Jarvis for £100,000. It was then resold to Metal Industries for breaking on the condition that it was done at Jarrow in order to relieve unemployment there. On 19 September 1937 the hulk was towed to Inverkeithing for final demolition. I suppose you want everyone to think that was the Titanic that was scraped out withot a single person finding out? At some point one needs to be realistic.
# The Olympic class liners, which cost about $7 million a piece, were under-insured. The ships were insured for $3-$4 million. Sinking the ships would have lost money, not made it.

# The ships were insured with the International Mercantile Marine. If they lost the ships, the insurance money would be coming from themselves.

# Harland and Wolff Shipyards have too many employees to keep such an undercover operation secret. Thousands of men worked on these ships. If the ships were switched, chances that every single soul taking such a secret to the grave defies belief.

Even with that anyone with any knowledge would have known the many features unseen by amatures in differences:

Physical Differences between Olympic and Titanic

* Different air vent arrangements around the funnels.
* Titanic was 4 inches longer than Olympic.
* Olympic's bridge roof was painted gray while Titanic's was bare planking.
* Olympic's breakwater was painted black while Titanic's was white.
* Olympic's keel number was 400. Titanic's was 401. These would be apparent on the ships' propellers.
* The propellers on the two ships had different pitches, and were therefore not interchangeable.
* Olympic's outdoor forward stairs had covers while Titanic's didn't.
* The porthole arrangements on Shelter Deck "C" between the two ships were different.
* The lounge furniture had the names of the ships on them.
* The forward third of Titanic's promenade on Promenade Deck "A" was enclosed. Olympic's was open all the way.
* The Reception Room on Saloon Deck "D" was larger on Titanic than Olympic.
* Bridge Deck "B" was drastically different on both ships. Olympic had a first class promenade whereas Titanic had two private verandahs and suites that were plush with the sides of the superstructure. The extra interior room on Titanic were used as rooms for a passenger's personal help. Also on Titanic, the second class promenade was eaten up for a larger À la Carte Restaurant and a Café Parisien. These modifications would result in Titanic having 1,004 gross tons (or 100,400 cubic feet) more enclosed space than Olympic.
* The carpeting patterns on both ships were different.
* Titanic had red carpet on her first class grand staircases, Olympic's were bare oak (supposedly).
* Another reception room was added on Bridge Deck "B" next to the À la Carte Restaurant on Titanic.
* The Officers' Deckhouse was pushed out more on Titanic than on Olympic.
* The painting in Titanic's smoke room was "Approach to Plymouth Harbour," while Olympic's was "Approach to the New World."
* Titanic was less dense than Olympic. Titanic's capacity was 3,295, while Olympic's was 3,547.
* Olympic had open third class berths. Titanic did not.
* The steel plating arrangement on the two ships were noticeably different.
* The name plates of each ship were brass that had to be screwed onto the hull. Had passengers seen Olympic when they boarded instead of Titanic, they would've figured out something.
* The layout of the Turkish Baths on the two ships were different.
* Titanic had extra first class cabins on Boat Deck. On Olympic, that area was all crew.
* Titanic had additional cabins on Promenade Deck "A" around the aft staircase.
* On Olympic, the wireless room was on the port side of the Officers' Deckhouse. On Titanic it was amidships.
