I edited my post to explain a little further but I guess we were posting at the same time. I understand the return leg was to be his last. I will check on that but I'm sure some of the others here know that off the top of their head. He made many runs thru ice fields. He probably didnt think it was any more risky than the other trips.If it was his last crossing why take such a risk through the icefield at speed?
If it was his last run how does he get back home?
