ice flight

My C-17 flight to Antarctica seemed odd compared to the last trips to and from New Zealand. Rather than a packed flight of 120+ passenger, I flew south with only four other civilian passengers. We each had any number of seats to ourselves. There wasn't a whole lot to see out our window but clouds and sea. I snapped a couple pictures of glaciers from the air as we passed over some of the continent, though. Most of the trip I was so exhausted, I slept. Much of this flight day I was also running over the following phrase in my head: "What am I doing?"
