There was like 4 feet gap between the ship and the iceberg which was causing them a lot of problems. Then they did something that made them reach the top of the iceberg. After they moved the ship little further away from the iceberg they brought the ship back near the iceberg but this time in the backward direction. Have you seen a room on the ship where a helmsman steers a ship? Then one of them reached the top of that cabin which helped him to reach the top of the iceberg. He saw that thing and shouted in shock. What did he see?
