Many residents of Inishowen, Derry and Letterkenny had their eyes to the skies last night as a plane charted an unusual flight path overhead.
The late night flight sparked questions over what the aircraft was up to.
The Beech E90 King Air model plane belongs to Diamond Executive Aviation [DEA], a UK-based company that carries out aerial surveys. Their services include offering flights for intelligence, surveillance and reconnaissance, aerial survey and specialist commercial air transport.
The mapping work was carried out at night due to ‘operational and technical’ reasons.
The plane took off from Birmingham after 9pm and, after zig-zagging over Donegal and Derry, touched down at Belfast International Airport at 3am.
