J. C. Kelly-Rogers, ‘Aviation in Ireland - 1784 to 1922’, Éire-Ireland, 6, 2 (Summer 1971), pp.3-17 reports that ‘[I]n 1896, the publication Nature reported that the Hon. C. A. Parsons had built a steam-powered model aeroplane weighing only 31/2 [three and a half] pounds and that it had flown a distance of 100 yards, rising to a height of 20 feet. Parsons, younger son of the third Earl of Rosse, was the inventor of the steam turbine; the factory bearing his name still makes them in Newcastle-Upon-Tyne to this day. A large photograph in Birr Castle, Co. Offaly, shows the model with fair clarity and efforts are being made to discover more about it. From its appearance engineers are of the opinion that it may have been a control line model and that it had VTOL capability (vertical take-off and landing).’ (p.6)
