Correct "satsuma", I stand to be corrected but the Guardia Civil has his own fleet and own pilots as they are a part of the Spanish Armed forces belonging to the Ministry of Defence.
For the non spanish speaking PPRuners the article and other sources state the helicopter rotors collided with the mountain wall while proceding to pick up a rescue specialist and a mountanier with a broken ankle at around 9.00AM. Two pilots and a third officer died in the crash. The 4th crewmember took also part in the recovery operation of the deceased.
In the news streem heavy fog is reported to have been in the area at the time of the accident.

Still a very sad day and a useless loss of life.
