The wreck of the RMS Titanic is located about south-southeast of the coast of Newfoundland, lying at a depth of about . Over the years since 1912, when the liner hit an iceberg and sank during her maiden voyage, many impractical, expensive and often physically impossible schemes have been put forward to raise the wreck from its resting place. They have included ideas such as filling the wreck with ping-pong balls, injecting it with 180,000 tons of Vaseline, or using half a million tons of liquid nitrogen to turn it into a giant iceberg that would float back to the surface.
