The last RAF squadron took off in a helicopter diamond formation from Aldergrove, marking the end of the RAF's 91 year history of flying from Northern Ireland.
The 230 "Tiger" Squadron made his journey to their new home base at RAF Benson in Oxfordshire on Tuesday, flying from Aldergrove across parts of Counties Antrim and Down before heading over the Irish Sea.
The distinctive diamond formation of Puma aircraft was witnessed by many people on the ground.
"The people of Northern Ireland have been very good to the RAF and sadly this marks the end of an important chapter in the RAF's history", Wing Commander Rich Maddison, the Office Commanding 230 Squadron said.
"This squadron could not have achieved all it has on operations over the past six years without the essential training we have been able to conduct in the Province and we shall certainly miss being here."
In September the RAF flag was lowered at Aldergrove and replaced by that of the Joint Helicopter Force.
