Sheila Dillon looks at some of the latest developments in airline food. The supply chain is beginning to open up and innovative producers from the north east of Britain have succeeded in winning contracts to supply leading airlines. One of these suppliers - 'Look What We Found' - has led the way in technology to deliver quality ambient food in a bag. They've converted this to a tray of food that can be heated and eaten during a flight. Gate Gourmet, one of the largest providers of airline catering in the world, has had its difficulties in recent years - strike action and radical restructuring. Now back on its feet it has just opened a new £10m production kitchen. Sheila Dillon visits the new facilities and sees for herself the challenges of feeding and pleasing millions of people a year consuming meals 30,000 feet up in the sky. producer: Lucinda Montefiore.
