Couldn't open exactly this video, so made assumptions watching other ones.

Otherwise you need a lot of bad luck that a capsule that only half an hour before was still airtight, will suddenly let water flow in. Link to comment Share on other sites More sharing options...

The capsule had inflatable balloons to stay floating. As also CST-100 has. Will CST-100 float endlessly without balloons? Upd: btw, enjoy: Spoiler Spoiler Huge (!) balloons, red raft, yellow jackets. Are they afraid of being lost in this pool? Or is it a solid standard for rescue equipment? Edited January 29, 2017 by kerbiloid Link to comment Share on other sites More sharing options...

Will CST-100 float endlessly without balloons? I quote wikipedia (https://en.wikipedia.org/wiki/Splashdown): Quote On early Mercury flights, a helicopter attached a cable to the capsule, lifted it from the water and delivered it to a nearby ship. This was changed after the sinking of Liberty Bell 7. All later Mercury, Gemini and Apollo capsules had a flotation collar (similar to a rubber life raft) attached to the spacecraft to increase their buoyancy. The spacecraft would then be brought alongside a ship and lifted onto deck by crane. The inflatable balloons were only added after the sinking of Liberty Bell 7. As to the question "Will CST-100 float endlessly without balloons?": CST-100 is designed to be airtight for more than 6 month in space, so there had to be something on the capsule which would get easily destroyed by seawater. The 6 balloons below the capsule are the same as those used to dampen the landing on land. So they are probably pretty tough. As to the 2 purple balloons on top, they are intended to right the capsule, if it flips over in the water, to allow for an easier recovery.

After landing/splashing, 6 humans need to breathe. 9 minutes ago, Tullius said: The 6 balloons below the capsule are the same as those used to dampen the landing on land. Exactly. They have a double purpose. And as you can see at 1:40, even with 6 inflated balloons, the CST-100 capsule is underwater at 1/3 of height or a half of its volume. 11 minutes ago, Tullius said: So they are probably pretty tough. Ocean waves occaionally break metal walls if a ship stays sideways. Here are just attached 6 plastic balloons. Also, as you can see, to pick the crew members from the capsule, they first must either slip down the capsule side, or to climb a rope. In both cases they can fall down into the water, and then you need to take them from water. Link to comment Share on other sites More sharing options...
mikegarrison Posted January 29, 2017 Author Share Posted January 29, 2017 Hey folks, I guess kerbiloid is right. It will be fine if the capsule sinks to the bottom of the ocean or crashes into a mountain or something if only the spacesuits are orange. That will solve all potential problems, no matter how unreasonable they might be. Link to comment Share on other sites More sharing options...

That is regardless of whether they are alive and fine, incapacitated or deceased, and whether they are in water, mountains, forest or desert. In all three cases their families usually want them brought home too. The colour of the suit is definitely the last and least link in the survivability chain, but that does not mean it is a good idea to make that link any weaker than it can be.
