Aircraft based at Lincolnshire's RAF Waddington have been giving high tech support to parts of the country hit by flooding.
The Sentinel R1 aircraft have been using high tech radar systems to give satellite imagery to help crews on the ground with their efforts.
They say: "The Sentinel system delivers all-weather tactical surveillance information, using powerful processing techniques to produce photo-like imagery of the ground from radar returns.
"These images will be converted in to large scale mapping to assist with strategic planning and early identification of those areas at the highest risk of further flooding."
One area they are looking at is the Thames Valley, which was similarly affected during floods in 1947, and by using the radar imagery, they hope it will shed light on areas which are prone to flooding, and help future relief efforts.
The media were invited inside RAF Waddington in Lincolnshire, to see how unmanned drones are operated.
They are one of the most controversial aspects of British defence - armed aerial vehicles flying over combat zones like Afghanistan - but guided remotely from the safety of British soil. Sally Simpson reports.
More aircraft are expected to descend on Lincoln today ahead of this year's RAF Waddington International Air Show. The event opens to the public this weekend and if previous years are anything to go by, will be attended by around 125,000 people.
