Scuba Divers Find Huge, Mysterious Object

A team of amateur treasure hunters went scuba diving recently in the Baltic Sea. They were exploring underwater near Sweden when they came across a huge, unexplained object. This object is not something natural to the ocean floor and is as big as a jumbo jet! The leader of the scuba diving team joked that he had found a crashed UFO.

No one has found an explanation for the discovery yet. It seems much too large to be part of an ordinary shipwreck. It also has a similar, smaller object nearby. Someone had a theory that these things were pieces of a giant Russian ship from the 1800s. However, those particular ships never traveled in that area. The team hopes to go back for a closer look at the mystery once the waters are calmer.

What do you think this team found?
