Hope the pilot and pax have a speedy recovery. Not going to comment about the pilots decision to continue the flight but maybe he learned something from this.
Quote from their youtube video - "Due to warming temperatures there was an increase in density altitude and we had a hard time getting adequate lift. After taking off we hit an air pocket that made us rapidly loose altitude, pushing us down into the trees."
