Before anyone's comments put you off the Cessna 172 please read this- also off Pprune 2011: see sheet three of the thread and read the story this guy leads you to.

A full report with lots of pictures is available.
"At the pole ....... on the 17th of July 2011, at 15.20 GMT, a little Cessna 172took off from Eureka (Canada), and set course North. After 6 hours of flying, at 21.25 GMT, this little Cessna was over the geographic North Pole, all alone, in a vast white emptyness. 6 hours later, the little Cessna made a safe landing back in Eureka."
