A ship and an airplane were dispatched to look for a missing submarine during Titanic’s debris survey. Searching over a few days is performed under severe conditions, and the terrain on the seabed is complicated, so it is expected to take time to search. However, if the submarine is found, Titanic remnant surveys may be further advanced, and there may be new discoveries. The members of the search team discovered a missing submarine and said that everyone would like to be happy. The search is still going on, so we will tell you as soon as new information is entered.
