Confirm the ownership of the helicopter as earlier and imply it is an Andorran company; though there seems to be a parallel company with a similar/ near identical name across the Andorran border in Catalonia.
The press speak of a dual-investigation due to the machine being French built but Spanish registered. [Does Andorra have a functioning Civil Aviation Authority or similar, I wonder ?]
A local paper "El Periodic de Andorra" describes the machine as the oldest in the company fleet and calls it an "Écureill".
The sling snagging the trees seems to be the dominant theory (though early reports did discuss other scenarios.)
