there where several flights over groenland during ww2 from the USA and Canada. remember a program on discovery where some plain nerds doug out a couple of american fighters that had ditched on the ice as they had flown themselvs wild.
They usually flew over groenland then to iceland then to europa due to shorter then today flight distance(range)

That programme was about the P-38 Glacier Girl and the lost squadron. The weren't lost, they were on a ferry flight from the States. HIt some real dirty weather as i recall and the whole squadron force landed on the ice.
