A plane has been spotted zig-zagging in the sky above Kent.

The bizarre path of the Pilatus PC-12/45 was captured on an online flight path map.

It can be seen travelling from Exeter before starting to zig-zag in East Sussex.

The aircraft then journeys up towards Kent - flying over Medway and Maidstone.

Flightradar24 show other aircraft making similar trips across the country.

But the reason behind these strange flight paths is because Bluesky International Ltd has been completing aerial surveys across the UK.

It keeps a three year update programme of vertical aerial photography in the UK and Ireland.

The data is licensed for applications such as planning, flood modelling, coastal erosion analysis, map production, civil engineering projects, forestry management and disaster planning.

Bluesky International was established in 2003 and is the UK's largest aerial survey company.

A spokesperson for the company said: "This is nothing new, I think people are just noticing the survey planes more as there’s currently less air traffic than normal."
