Arthur Ord-Hume ('British Private Aircraft 1946-1970', Vol.2 'An A to Z of Club & Private Aeroplanes' (MMP Books, 2013)) says that Ray Hilborne's design was originally known as the Hornet and then became the Hampshire Aero Club HAC.2 Halcyon, but when it was registered as G-ARIO, on January 31st 1961, it was titled the Bellamy Hilborne BH.1 Halcyon. The damage suffered in taxiing trials was severe, namely a fracture of the centre section rear spar (which Ord-Hume blamed on 'Eastleigh's rather rough, rabbit-hole-pocked surface'), which rendered the Halcyon beyond economic repair and thus the project was abandoned, resulting in the aeroplane being put into storage and eventually its remains were burned.
