Audio problem: The ship is going at full speed towards the coast - making a roaring engine sound. But when it hits the coast and stops, the sound of the engines stop too. Who turned them off? (01:46:25)
Audio problem: When the light towers are running in the base camp, the lights are on but the generators running the light can't be heard running. They look like AL4000 Terex list plants, diesel motors on the generators are super loud.






Answer: It's basically about facing one's own mortality. Many humans feel that they 'feel the most alive' when facing (and overcoming) dangerous situations, the more challenging, the better.
