I've flown in one of those planes. They have a reputation for being incredibly reliable and safe. That plane is credited with opening up the Canadian North, due to the a/n factors. I just remember that the plane was incredibly noisy (single radial engine) and that I had to help the pilot add oil in mid flight. Judgin by the video, it doesn't appear that the pilot generated enough airspeed to even consider taking off.
I do remember a few flights where the pilot was worried about weight. It would not surprise me if that plane was repaired and back in business in a few weeks. It's a tough plane that's been around for 60 years.
