History

William Beardmore and Company had acquired a licence for the use of the Rohrbach principle for stressed-skin construction. Using these principles, the company designed what was then a massive all-metal three-engined transport the "Beardmore Inflexible".

The aircraft (Serial Number J7557) was built at Dalmuir between 1925 and 1927 and was roaded to Martlesham Heath Airfield where it first flew on the 5 March 1928. The aircraft appeared at the Hendon RAF Display in 1928. The aircraft was structurally advanced for its time but was underpowered. The aircraft was dismantled at Martlesham Heath in 1930 and used as test airframe to investigate the effects of corrosion.
