While completing naval exercises with dummy torpedoes on August 12, 2000, the Russian submarine Kursk suffered two explosions two minutes and 15 seconds apart. The second explosion registered about a 3.5 on the Richter scale. The blasts destroyed the front hull, and all 118 crew members died. It was initially believed that the entire crew died quickly. However, what evidence later suggested that some survived in another area of the submarine for about four hours after the explosions? Discuss
