A tener en cuenta, a partir de ahora:
Assuming the sub is found, how will crew members be rescued?
Even if the sub is located it could take several days to get a rescue vessel there, Graham said. This is problematic when oxygen supplies are diminishing, especially when surface conditions are so rough.
"It's difficult to operate in 8-meter (26 feet) waves," he said. Adding to the difficulties of a rescue, we currently "don't know what depth it is located, (and) how precarious the state of the hull could be."
The condition of the sub, assuming its resting on the continental shelf, is also of key concern.
"The sunk submarine needs to be sitting upright -- or nearly so -- on the sea floor so the rescue hatch(es) can be easily reached and docked with," Layton said. "The sea floor, though, is not flat. If the submarine is lying at an acute angle, docking could be hard."

Traduzco: Asumiendo que el sub es hallado, como se rescata a la tripulacion???
Rta: Aun si el sub es localizado, pueden tomar varios dias para que los buques de salvamento esten en zona. Esto es problematico cuando las reservas de O2 estan disminuyendo, en especial cuando las condiciones del mar son severas.Es dificultoso operar con olas de 8 mts. Agregando dificultades al rescate, usualmente no sabemos a que profundidad esta y cuan precaria es la situacion del casco. La condicion del submarino, asumiendo que descanza sobre la plataforma continental, es tambien motivo de preocupacion. El sub hundido necesita estar posado derecho o casi sobre el suelo marino para que los dispositivos de rescate puedan alcanzarlo y quedar amarrados a el. El suelo marino, ademas, no es plano.Si el sub descanza en un angulo agudo, el amarre de los dispositivos de evacuacion, podria ser dificil
