The lengthy undercarriage came about from the mini Stirling's high landing speed and long take off and landing run. The answer was to increase the main wing's angle of incidence, but because the prototype Stirling had its wing already positioned when this was found out, the solution was to steepen the ground stance using a long main gear.
Initially, the S.29, Short's original entry to B.12/36, to which the firm was not on the list of tendering companies, was described as 'a robust effort but too near flying boat design'. It was considerably modified before the final design was settled on during the Mock-Up Conference in December 1937. CAS recommended that Short build the S.29 as insurance in case of failure of the Supermarine 316, because it had experience in four engine aeroplanes (flying boats).
The Stirling might have had flying boat DNA, but structurally, it had nothing in common with either the Empires or the Sunderland. It was conceived around the concept of modular construction, where each segment was built as a single unit then mated together, supposedly for ease of production, although the prototype ran six months behind schedule, then crashed before any performance trials were carried out.
