On September 13th, Time magazine (click) informed their readers that "Northwest Passage's navigability was dramatically demonstrated".
Two ships coming from the opposite directions met and astonished Eskimo cheers from both crews echoed through the rock-bound channel. ;-)
The only problem is that it was not September 13th, 2008 but September 13th, 1937. :-) Well, it shouldn't be too shocking because the current Arctic temperature is pretty much what it was in the late 1930s.
