So that we can all learn-
From another site:
"The video seems to document an accident in ID in June (NTSB report here; news account here). The aircraft in that accident was a Stinson 108-3.
According to those reports, the departure airport was Bruce Meadows Airport (U63), Stanley, Idaho, elevation 6370. Google Earth view here.
The investigation has only begun, but the video appears to show one hazard associated with operations at high density altitudes, viz., that you may be able to take off, but you may not be able to outclimb terrain and obstructions."
The video is chilling in how benign it seems until there is a problem.....
