“Mysterious” helicopter flights over Sarrabus, comes the explanation

In recent days it had become a case. Residents wondered why helicopters were constantly crisscrossing the skies over Sarrabus .

The explanation came from the AvioCastiadas association, which explained that it is a study by the University of Cagliari . The university, in fact, is identifying and monitoring the aquifers of the area through a system of sensors.

The sensors, linked to the helicopter with special cables, are capable of detecting up to a hundred meters of depth.
