The article says they took of around 3:30 in the afternoon. Altitude of that airport is 6,370'. I wonder what the density altitude was that day?

Temps in that area are currently running in the mid to high 90s.
On June 30th, I would have expected similar temps, putting the DA at around 10,000.
The plane is a 165hp Stinson 108.
With an 1100 lb useful load, he should not have been overweight with 3 teenage boys in the plane. But your useful load, iirc, is determined at sea level. My guess is that the DA, load, and reduced hp at high altitude, all worked together to create this result.
More accurately, what created this result is pilot error.
When you take most of a runway that is nearly a mile long, you should have known there was a problem. Takeoff roll for a plane like this should only be about 602 ft at full gross wt.

No relation to me, Doug!
Last year we were discussing a different Stinson. Remember this one?
