You're welcome Maurice!, glad someone found it interesting.
It was definitely an experience and would go back if I could. Awesome landscapes, Scotts hut, pengiuns, seals, killer wales, colbalt blue ice/ice bergs, helping science.
Most of my time there was between Willy field skiway which was about 8 miles from McMurdo and located on an ice shelf, and the ice runway over annual sea ice. Back then, the ice runway was about 10' thick sea ice that wheeled planes like C-130's and C-141's could use early in the spring (our fall) until the ice would get too thin and begin to breakup. At that point only planes with skis would begin using Willie field which was on thick snow, over ice, over water. That Williams field was named after a guy that died when his D8 tractor fell thru the ice was a bit of a constant reminder of some of the hazards.
I never made it to the dome at the pole but did make a early flight to dome Charlie which is not a geodesic dome but a land formation at about 10,000' high on the Antarctic plateau. That day, from altitude it looked like dry ice with it's low hazy vapors, after the open field landing it looked about the same. The "vapors"/haze were just ice crystals, baby snowflakes. I don't know what the temp was there that day but remember thinking it felt a lot colder than -40 i had seen at willie field
About 2 weeks later one of our C-130's crashed at Dome Charlie while using jato during takeoff. Jato are rocket bottles strapped to the fuselage of the plane for additional thrust. One of the jato bottles broke from it's mooring and went thru one of the wings. One of the rescue planes also crashed taking off from there. Its nose ski started to bounce on the rough ice, the front ski strut broke and the plane plowed into the ice and snow.
As i understand it, later a third plane sent with a tractor and equipment to repair those planes also crashed due to a Jato issue. Eventually all of the planes were repaired enough in the field to fly out for additional repairs and go back in to service. Here's a link for those interested in those crashes and repairs
