SP, thanks for fixing the Youtube links!
Here is the location:
Google Maps The landing zone was in the inside of the 90° turn of the road in the middle of the map, so the elevation is approx 1480m.
Local map with elevation According to the local meteo data, I would guesstimate the temperature was 15-20°C and there wasn't much humidity.
Three persons on board, possibly with equipment, since the helicopter was supposed to help ground crews fighting a forest fire nearby.
The helicopter had taken off from the airport in Pescara, approx 40 km away, so the fuel tanks might have been more on the "Full" side.
