Why is it so hard to find the lost Titanic tourism submarine?
(inspired by a question on reddit, I'll post a reply too)
You're viewing a single thread.
Short answer: ocean is very big, submersible is very small.
Long answer: Imagine going out on a football pitch with a white paint marker. Randomly walk around and pick a single blade of grass to paint white. Now grab someone that didn't observe you and tell them to find the painted blade of grass. Also tell them they have a limited time, and that you might have pushed the blade of grass doen into the ground.
There has to be a solution that would have allowed them to send a buoy up to transmit a mayday and coordinates like some life boats do. This would help the rescue teams to narrow the search grid. I wouldn't have gone down in that thing, but if I WAS, I would at least feel better with something like that.
they were two miles deep. sending up a tethered buoy means holding two miles of string on the sub, which would be completely impractical. sending an untethered buoy doesn't really help anything, because by the time it goes two miles up to the surface, it could have drifted way further than that in any other direction.
