Early morning on July 15, 1942, two squadrons of Lockheed P-38s escorting a Boeing B-17, were airborne on their way to Iceland. Hampered by bad weather and low on fuel, they were forced to land on the eastern coast of Greenland. After several days the pilots were rescued and planes were left to be recovered at a later date.
In the spring of 1992, a group of 40 people led by Middlesboro entrepreneur Roy Shoffner returned to Greenland and burrowed through 268 feet of ice to reach one of the Lockheed P-38s and brought it up piece by piece to the surface.
A decade later, on October 26th, 2002, after thousands of hours of work the P-38 they recovered, now dubbed "The Glacier Girl," took flight again.
268 feet of ice in 50 years seems like a good rate of accumulation to me.
See, global warming climate change is happening.
