Supplied The Reeve family make their way to the Hopkins Valley. Talking to witnesses and friends of the pilot, Brian Chadwick, they believe they're in the right spot. "He would have known roughly whereabouts he was and properly entered the cloud thinking he was high enough to get through the pass and he's been off to one side or the other. "When you look at the area up there, it's an area where nobody would go, no-one would just stumble across it." Reeve said the discovery of a woman's boot in the remote location has led them to believe the plane was about 8000 feet up, deep in the permanent snow.
