A photographic look at the history and development of the difficult and delicate process of in-flight refuelling.

Keith Wilson has been involved in aviation publishing for more than 30 years and is probably best known for his striking air-to-air images in Pilot magazine. He has more than 1,500 air-to-air sorties under his belt, shooting almost 2,000 different aircraft in the process. He has photographed a very broad range of subjects, from gliders, vintage and veteran, aerobatics and general aviation right through high-altitude research aircraft, biz jets, commercial jets and military fast jets. During this time he has amassed a photographic library of around 300,000 images. He has worked for a number of well-known aviation companies across Europe and flying is also his hobby. He obtained a Private Pilots Licence back in 1981 and continues to fly at every opportunity.
