There was another busy night in the sky disturbing our sleep on Wednesday night 26th/27th May. A small Reims-Cessna F406 Caravan II plane which originated in East Midlands airport spent a long time in the air over Monaghan/Fermanagh, with the flight pattern similar to one in the same area on Saturday 24th April from a Cessna 404 Titan aircraft; both planes were owned by Reconnaissance Ventures Ltd (RVL Group). It is presumed that a night survey was being carried out, with the flight taking advantage of the clear skies, the low leaf cover on trees, and the relatively low volumes of air traffic. The sensors on board collect data in ‘strips’ of varying width depending on the resolution of data required, hence the up and down flying patterns. These ‘strips’ are then joined together to produce a complete survey of the area being studied. These flights can collect thermal data, LiDAR modelling, and Colour Infrared (CIR) imagery, and geochemical and geophysical data on rocks, soil and water. RVL based at East Midlands airport are one of the UK leading expert on aerial photography, surveying, and mapping, and after hovering over the local skies, it headed off down the midlands, before returning to the UK.
