If you have seen an aircraft tracking back and forth in the skies in recent weeks you might like to know it is mapping power lines and trees to help prevent power cuts.

The Danish Vulcanair plane has been spotted above the Isle of Wight, Hampshire and West Sussex in recent weeks, prompting speculation about its purpose.

A spokesman for NM Group, a specialist in scanning power lines, said it was using 3D scanning technology to identify vegetation near power lines in Scottish and Southern Electricity Networks’ central southern England network area.

He said: "Identifying vegetation that is too close to the network, in this way, helps ensure that SSEN field teams can complete targeted tree trimming and maintenance work. This proactive tree management reduces the chance of service interruptions."
