A particular period of Rob Milne's professional contact with Industry that many of his academic colleagues and friends may not be familiar with is that during which he provided consultancy to British Airways. Rob became involved in a number of projects carried out by the British Airways Artificial Intelligence Unit from the late 1980's through to the late 1990's. The following is an account of some of the more important project areas that Rob and his colleagues from Intelligent Applications participated in, as well as highlighting the important contribution that he made to many of the business decisions required of the Artificial Intelligence Unit in developing knowledge-based solutions for the airline, and to the industry in general.
