i watched this thinking it would be interesting..but found it pretty poor and the over the top dramatics just made things worse..like when they were diving in the lake the lake could drain at any time so we have attached life lines to the divers..no sh*t einstein..and it seems the sea it self could be another cause for the calving of icebergs..no really?..water flowing to the bottom of the glacier and gravity seem to be the cause of why the glacier is moving..id never have guessed?..and whats the doc doing there?..i know lets do an experiment as to why mosquitoes bite more people than others..now your just wasting my time!!
