The quality of the 2nd wire is a bit better than the first. If you listen real careful (with headphones) you can hear a faint "chu-chu-chu" sound. That's the sound of the props of the I52.
Later, you hear the Fido dropped and then the loud explosion when it hits the sub.
Following the hit, you hear a repetitive "tink-tink" sound. This is the sound of steel rupturing as the hull comes apart under pressure.
The I52 has recently been found at 5500m. They are investigating whether they can recover her and return her to Japan. The two tons of gold on the manifest may be influencing the decision.
