As a skydiver, I think it’s important to note he didn’t have an emergency chute but a regular sport one. They are extremely maneuverable and if there is a small clearing or riverbed nearby (he looked down for such a thing) the risk of injury is nearly non existent for an experienced skydiver.

The whole thing looks planned, but if I were in the same situation I’d definitely be jumping over trying to crash land a cheap plane in a riverbed or clearing.
