When drones help to cop thieves...

To fight against copper cable theft on its railway network, the French railway company the S.N.C.F. recently called in the help of drones ! In early February, a Delair-Tech "DT-18" overflew a section of railway tracks for 2 hours, at 50km/h and at less than 150 metres above the ground; a world's first for a civilian drone.
