Hmmm... I've lived in a place that received around 500 inches of snow per year. If that snow did not melt (it did where I lived, thankfully) and if compressed to 10 percent of its original depth to account for lost interstitial volume, we arrive at an ice depth of around 4 feet. At four feet of accumulation per year for the intervening 60 or so years, the resulting figure is quite close to the 250 feet you've mentioned. I guess I've missed your point.

You've missed the point alright. Show us where Greenland gets 500" of snow a year, especially at the exact spot where the planes landed.

Then perhaps, you could explain why they traveled a mile from their original location.

See Glacial Movement.

I doubt that snowfall accumulation data from the crash site is available. What I was pointing out was that accumulation of ice is not startling. For material upon or within a glacier to move is also not remarkable; glacial flow can be many miles per year.
