A synchronised display which was a joint voluntary effort between Safehaven Marine and Atlantic Flight Training Academy in Cork to lift the mood on St Patrick's Day when Safehaven Marine's ThunderChild 11 roared past Cobh, Co. Cork, as AFTA's Slingsby T67 Firefly, a two-seater aerobatic aircraft to train commercial pilots, flew 700ft overhead. Picture: Dennis Horgan

One of the world’s fastest powerboats and an aerobatics plane with links to Prince Harry performed a dramatic St Patrick’s Day surprise synchronised display in Cork Harbour in a bid to lift spirits.

While thousands would normally have lined the streets of Cobh for its traditional St Patrick’s Day parade, people in the harbour town were treated to a thrilling sail-by fly-by spectacle.
