I reported the trouble of the Japanese submersible "Shinkai 6500".
She could not dive donw to deep sea.
The famous submersible "Shinkai 6500" >> see details (in Japanese).
She has a titanium pressure sphere with diameter of about 2m.
Three people can ride into the sphere.
The hatch at the top of sphere had a trouble.
"Hello! I'm a pressure sphere!"
(not like "The Scream" by Munch)
