On the Thursday night of the 10th January 1952, Aer Lingus Flight EI 165, en route from Northolt (London) to Collinstown ( Dublin), crashed in the Snowdonia mountains. All of the 23 occupants were killed. Four months later, the British Government held a public inquiry into the crash of the 'Saint Kevin' airliner. Shortly thereafter, they issued a report detailing the causes of the crash. Adverb Transpositioning In the sequel to the 'Shamrock 165' trilogy, 'Thy Will Be Done', Gawain Cymraeg, offers compelling evidence as to what really unfolded in the skies above Snowdonia, almost 72 years years ago. A question the author was frequently asked was, 'how could they have left our loved ones in a watery-bog-hole atop a lonely mountain?'. Cymraeg attempts to address this question by trasnposing the adverbs, 'how' and 'why'. Coupling the end result with the 'root of all evil' produces some surprising - or perhaps, unsurprising results.
