A paraglider who was found dead in Co Wicklow in May died of a heart attack, a report has found.
The pilot launched from a location at Sorrel Hill with the intention of conducting a cross-country flight to Wexford town.
A fellow paraglider pilot also witnessed the launch on May 11th.
The pilot gained height and then proceeded in a south-easterly direction towards the Glenmalure Valley.
A mobile phone app used by the pilot showed the entire flight - from the launch point to the north slope of Ballinacor Mountain.
The pilot did not reply to a phone message sent later that day, and was declared missing.
His body was found on May 12th on Ballinacor Mountain, still attached to the pilot's seat harness.
An Air Accident Investigation Unit (AAIU) report says he had been airborne for one hour and 33 minutes.
It says the paraglider wing was recovered, deflated on the ground, and all lines were on the surface - untangled and undamaged.
The reserve parachute was also unused and the activation handle was in its normal position.
A post mortem report was made available to the AAIU investigation by the Coroner for Wicklow East.
It stated that 'no fractures were identified' on the pilot, and toxicology tests found that drugs were not detected.
The cause of death is listed as acute myocardial infarction, due to coronary artery thrombosis with atheroma.
Prior to becoming involved in paragliding, the pilot had been a skydiving instructor in Poland, Ireland and the United States.
