The c-130s have been busy being loaded with cargo headed to the South Pole. I heard a few guys saying today that they can't wait until the majority of the South Pole stuff is shipped down because they are just freezing out there. Thank goodness for chili and coffee eh boys? I keep 'em extra hot. 
The plane above is only 1 of 2 of their kind in operation. Most of the Hercs have 4 blades per prop, but this on has 8. It's quiter, faster, and if one blade breaks they can rip it off and the prop will still function. It's a test here at the ice to see how it fares.
