Brazen & bold, evolutionists continue to interpret ice layers as an "annual" phenomena, although there is pretty clear evidence they are no such thing.

The Glacier Girl is one of a group of six P38's and two B-17's known as the "Lost Squadron". These planes ran low on fuel and ditched in Greenland in 1942. She is the only bird recovered thus far, and has been restored. It's not easy to recover these aircraft, due to the build-up of ice.

After many years of searching, with better detection equipment, they finally found the airplanes in 1988 three miles from their original location and under approximately 260 feet of ice! They went on to actually recovered one of them (“Glacier Girl” – a P38), which was eventually restored to her former glory.20

What is most interesting about this story, at least for the purposes of this discussion, is the depth at which the planes were found (as well as the speed which the glacier moved). It took only 46 years to bury the planes in over 260 feet (~80 meters) of ice and move then some 3 miles from their original location. This translates into a little over 5 ˝ feet (~1.7 meters) of ice or around 17 feet (~5 meters) of compact snow per year and about 100 meters of movement per year. In a telephone interview, Bob Cardin was asked how many layers of ice were above the recovered airplane. He responded by saying, “Oh, there were many hundreds of layers of ice above the airplane.” When told that each layer was supposed to represent one year of time, Bob said, “That is impossible! Each of those layers is a different warm spell – warm, cold, warm, cold, warm, cold.” 21 Also, the planes did not sink in the ice over time as some have suggested. Their density was less than the ice or snow since they were not filled with the snow, but remained hollow. They were in fact buried by the annual snowfall over the course of almost 50 years.

AiG has a a couple of short pages on the story

I think a little common sense goes a long ways when considering assumptions that marks of a given type are "annual" phenomenon. It should first be established that the marks are indeed the result of years passing - not something that may or may not be annual.

Kent Hovind does some math and calculates

Let's do some arithmetic.
* 263 feet divided by 48 years, that's an ice growth of about 5.5 feet per year.
* Now divide 10,000 feet by 5.5. And you get 1,824 years for ALL of the ice to build up.

We should allow longer for the fact that the deeper ice is pressed into finer layers.

Note: those planes did not sink into the ice, due to pressure on the ice. The ice had grown OVER them.

ARE THESE ANCIENT AIRCRAFT IN ICE?

Okay, would you do some maths? Can you work this out?

The Denver National Ice Core Laboratory said that 10,000 feet of ice had to be 135,000 years old! So the 263 feet deep of "Lost Squadron" ice - how old should that be? That's right, 3,419 years old.

One can think of all sorts of fun tricks to play. Take a simple hatchet or piece of pottery or bone to Antarctica & drop it. Return 50 years later & give evolutionists fits!

But as my second link explains, the ice data has become heavily politicized in support of "global warming". Don't expect anyone to give up pushing this misinterpretation any time soon. I have some suspicions that global warming may be half legit (we could still be emerging from an ice age), but cases like this don't inspire confidence in the data - quite the opposite.
