Only one day of delay in Christchurch due to weather - but it wasn't weather in McMurdo - it was the cold, windy, wet, turbulent, icy air over Christchurch that kept us grounded. Apparently LC-130's don't deal well with icy conditions.
The secret benifit of this delay was that we got scheduled to fly down on the big, noisy (but faster and more comfortable) C-17 instead. The same big fat jet that I've always taken to get down to the ice.
About 80 of us boarded it for the five and a half hour journey south.
