off track

Above, a McMurdo common drive photo of the track of the unfortunate aircraft. This happened near Upstream D (81S-140W) on 16 November 1998. An account by Bruce Blackburn:

As the aircraft was taxiing after drifting the cargo the pilot was trying to find a better takeoff route. She felt the bump as she landed across the crevasse. the nose ski bumped and she hit full power on all engines. The right ski dropped in and #4 hit the snow. The ski jumped out but the left side was not so lucky. They had to replace three engines on site and all 4 props as a precaution. The crevasse was not uncovered as you see in the picture 'till the salvage crew got on scene. They filled the crevasse with snow and used a bullbag to get the ski out of the crack. Note; I had ridden this aircraft to and from Downstream Charlie two weeks before the incident. A week after I returned the afore mentioned pilot had come in to the Ice runway with a quartering tail wind and ground-looped the aircraft off of the runway. She didn't return to the Ice this season.

And I should also note that the firebirds.org website, the source of a couple of the above links, covers the 17th Tactical Aircraft Squadron and its successors. This was the USAF group that flew ski-equipped Hercules aircraft to Pole a year before VX-6 acquired any.
