Late last year I had the pleasure to visit Hybrid Air Vehicles, a company based at the purpose-built and now listed Cardington hangars near Bedford.  The feature has now been published in ‘Strategies for Growth’, a  business magazine published on behalf of the accountants, Grant Thornton by Seven Publishing.  The hangars are spectacular, but perhaps not quite as spectacular as my brief to think in terms of black and white – my first such commission in many years!
