Gerd and Dorothy Wengler have visited Iqaluit twice so far in their Turbo Skylane.  The first trip was a stopover on the way to Ireland in 2005, the second for a sightseeing trip in 2007 to Pangnirtung, Qikiqtarjuaq and Greenland.

Gerd has written a very thorough trip report on their 2005 trip, which you can read here.

The summer of 2009 saw them on another arctic single engine adventure.

They joined the very small group of pilots who have landed their private aircraft at Canadian Forces Station Alert, the most northerly airport in North America. Alert is a restricted military site, so just getting permission to go there takes a lot of work.

And then there's the flight to the top of Ellesmere Island, some 4000 kilometers north of their home near Toronto, Ontario . There is only one small civilian community on Ellesmere - Grise Fiord, about 700 kilometers south of Alert. And there's a weather and science station about halfway up at Eureka. Making that trip is not something for the faint of heart.

Gerd and Dorothy made the Alert trip in mid-August 2009, from their home in southern Ontario.  And from this article on the Canadian Forces website, it sounds like it was quite an adventure.  They made the trip to mark the Centennial of Powered Flight in Canada.
