Gardiner further hypothesizes that the ship that was hit by the "Titanic" was the one seen by the SS "Californian" firing distress rockets, and that this explains the perceived inaction of the "Californian" (which traditionally is seen as failing to come to the rescue of the "Titanic" after sighting its distress rockets). Gardiner's hypothesis is that the "Californian", another IMM ship, was not expecting rockets but a rendezvous. The ice on the deck of the "Titanic" is explained by Gardiner as ice from the rigging of both the "Titanic" and the mystery ship she hit. As for the true "Titanic", Gardiner alleges that she spent 25 years in service as the "Olympic" and was scrapped in 1935.
