...was there somebody that tried to recover planes that went down in Greenland known as the Lost Squadron and they were expecting the ice to be 10 feet thick or less (according to scientists' best estimates). When they got there, they found that the planes were 268 feet deep.
This was between 1942 and 1992.
Umm, don't objects placed on the surface tend to 'sink' into ice caps ? Gear and huts built on the surface slowly descend into the ice as the years pass. So the P-38s sank down, as well as each years snow/ice deposit being layered on top of them. IIRC isn't the sink faster than the accertion of ice ?
