There's a transcript of some text messages which may or may not have been sent between the unfortunate submersible and the support vessel. Apparently the submersible was initially sinking at about 37 m/minute average, late in the dive accelerated to 45 meters/minute, instead of the expected 25 m/minute. I am wondering if (IF this transcript is legit) the submersible either had attached too much weight/ballast OR some of its bouyancy devices were compromised. Apparently the submersible dropped all the weight it could, including the landing frame and only acheived an ascent of about 5 meters/minute.
Anybody able to look at the math? I don't know anything about the math needed for calculating drag/velocity in water. How much bouyancy was lost to cause this?
Again: I don't know if that transcript is genuine or bogus.
