That must be a nightmare. The costs to repair that must be astronomic when you take into account the location.
Quite probably, but the insurance Company or the US taxpayer will probably be paying as it was on charter to the NSF.
Also as you are not allowed to leave
anything at all permanentlyon the antartic continent, cost may not actually come into it. I seem to recall a Discovery programme implying that even sewage has to be repatriated from the South Pole base.......
Not sure just how serious they are about that requirement, but I'd reckon that scrapping a plane full of fuel, oils & various toxic/semi-toxic fluids & other potentially polluting materials by the normal means are not going to be acceptable in this case.
