The “estimate of ice loss” should be labeled “estimate of ice gain”. Glacier Girl landed and was left behind on the Greenland ice sheet in 1942. She was recovered from beneath 270 feet of ice 50 year later: http://en.wikipedia.org/wiki/Glacier_girl How on earth did that aircraft get under 270 feet of ice in 50 years (5.4 feet of ice per year) if the ice sheet is shrinking?

Do heavy objects that are surrounded by ice “sink?”

I think its a question of the pressure the aircraft makes in contact with the ice, coupled with the conductivity of aluminum skin/frame...causes the ice to melt under the plane and the water to run off...so plane slowly sinks into the ice

like an ice skate blade is lubricated by melted ice as it passes...
