SoD… Hindsight is a wonderful thing!! In retrospect clearly lighter than air airships were a fundamentally flawed concept. However at the time the concept probably seemed viable. …

Very true, but my point is there was plenty of experience of airships by 1928. Many disadvantages had appeared, like what to do with 928 tons of sludge! Although lighter than air seems simple and obvious, the long list of awkward problems have thwarted attempts to produce a large commercially successful airship to this day.
Other governments abandoned rigid airships in the same time-frame:
- France – 1919
- UK and Italy – 1928
- USA – 1933
- Germany – 1937
- USSR – 1938
Dirigibles and blimps are useful. Small airships are handy when an aircraft has stay up for a long time in much the same area. Surveillance of the US/Mexico border and Caribbean drug smuggling routes, supporting the antenna used to broadcast TV into communist Cuba, and non-intrusive filming of sports come to mind. They're popular for tourists too. These are all niche requirements, otherwise airships don't compete well with alternatives like helicopters, satellites, drones, and slow flying fixed wing aircraft. Maybe the future will tip the balance back in favour of general-purpose rigid airships, but I doubt it.
Neville Shute's views on the R100 / R101 debacle have to be taken with a pinch of salt. He was emotionally involved. Proud of his achievements, and utterly convinced the Vickers design deserved to win, I think he lost sight of the real problem, which was no airship could deliver what the customer wanted. It didn't matter how well-made the R100 was. Engineers suffer from a lack of perspective, often thinking that technical excellence is enough. Nope! technical excellence is only part of the story. More important that products are fit for purpose, affordable and customers want them.
It's often difficult to judge whether decisions involving complex projects are right or wrong. Although I'm confident airships were a dead end, I'm not so sure about TSR-2. Although horribly late and over budget, it was cancelled in favour of aircraft that didn't meet the requirement, that in turn also suffered long delays and cost-overruns. It was a mess and the RAF had to wait for the Tornado before getting an aircraft that did the job in full.
Unfortunately, paying for the TSR-2 assumed it would be sold abroad, so when Britain's allies got fed up waiting and bought F-111's instead, the project became unaffordable. On top of that, although the airframe was well developed, the electronics and weapons systems weren't. Faced with not knowing how long the project would take or how much it would cost, it's not surprising the customer pulled the plug. But cancellation might well have been a mistake. We shall never know.
