Ghost Net Snags Sub

I've been following this Russian sub story and couldn't help but notice part of the reason they got stuck was from 'Ghost Nets' (fishing nets that have been released in the ocean).


Netting and cables got wrapped around the mini-sub's propeller

I've probably posted a few times on the continued death this nets cause in the seas with marine life, but this is the first time I recall hearing about people getting stuck in them. What a problem. Glad they are ok though. That was close.
