The Suburban Sub

I like to try and see through other people's, why they've made these videos. So I don't feel that other people are less moral than me or care less than me. The sub had seven different safety features that were meant to pull it back to the surface in case something happened. But all seven features to fail, something big had to happen to the sub. If it was going to fail, it would be failing deeper than if it was likely to have a catastrophic failure. This is why I think it's a conspiracy. It imploded when they lost communication.
