Response Article
This article (WWII airplanes are now beneath thousands of "annual" ice layers (Talk.Origins)) is a response to a rebuttal of a creationist claim published by Talk.Origins Archive under the title Index to Creationist Claims.

Claim CD410:

Ice cores are claimed to have as many as 135,000 annual layers. Yet airplanes of the "Lost Squadron" were buried under 263 feet of ice in 48 years, or about 5.5 feet per year. This contradicts the presumption that the wafer-thin layers in the ice cores could be annual layers.

CreationWiki response: (Talk.Origins quotes in blue)

1. The airplanes landed near the shore of Greenland, where snow accumulation is rapid, about 2 meters per year. Allowing for some compaction due to the weight of the snow, that accounts for the depth of snow they are buried under. The planes are also on an active glacier and have moved about 2 km since landing. Ice core dating takes place on stable ice fields, not active glaciers. The interior of Greenland, where ice cores were taken, receives much less snow. In Antarctica, where ice cores dating back more than 100,000 years have been collected, the rate of snow accumulation is much less still.

Talk Origins is making the assumption that neither the interior of Greenland nor Antarctica were ever active glaciers. It is quite likely that they were in the past, particularly given the conditions immediately following the Flood. Furthermore, Talk Origins omits the fact that the planes were also under hundreds of layers of ice, so all it would take to get the observed ice in both the interior of Greenland and Antarctica would have had much higher snowfall rates in the first 1000 to 2000 years following the Biblical Flood. So the area where the "Lost Squadron" was buried is a good model for past conditions in the areas where ice core dating is done, even if it is not for their present conditions.
