Ice-bound plane flies again!
‘Glacier Girl’ reminds us that it doesn’t take millions of years to form deep layers of ice
by Carl Wieland
The fascinating news that one of these magnificent ‘planes in ice’ is actually flying again brings to mind their whole amazing story. It is a powerful, real-life testimony against the widespread belief that it takes vast timespans to lay down thick layers of ice.
AIG claims "they turned out to be buried deep beneath some 75 metres (250 feet) of solid ice." as well.
Another reminder of how misleading (even dishonest? ) that these souces can be. This was, I think, all discussed once here but it could use a focussed thread of its own.
Craig has done enough messing up of the Correlations thread. Let's keep this one focussed a bit.
To start with the AIG reference neglects to get clear just where the aircraft in the ice are located relative to the ice core dated samples are. There is a difference in the amount of snow that falls in the two places.
The ice cores are located at 72.6 N 38.5 West. This area gets 20 to 30 g/cm^2/yr of preciptation. The planes went down at 65 20' N, 40 20' W where the precip is greater than 80 g/cm^2/year (I can't find anything saying how much greater.)
(see http://< !--UB
EvC Forum: glaciers and the flood -->
http://EvC Forum: glaciers and the flood -->
EvC Forum: glaciers and the flood< !--UE--> for maps of precip amounts)
The minimum of 80 g/cm^2/year produces 49 meters of solid ice in the 55 years from 1942 to the 1997 AIG ariticle. Of course the AIG talk of 75 meters of solid ice is wrong. The upper layers will not have turned to ice. That takes a few years. The depth of the planes is therefore close to what one would expect at the location.
The 75 meter depth is NOT layers of ice. There was no measurement of the annual layers that the planes were under.
The seasonal layers are, just like the varves, marked in the snow .
There are several different ways of determining that.

As usual these creationist sources tell a small part of the story and ignore the rest.
The lost squadron says nothing about the validity of the GISP2 and other ice core measurements.
