The story of the formation of the Aeronautical Information Group differs from that of the other groups in that we had to persuade the Director of Aslib of the necessity of forming such a group. He felt doubtful whether there were in Aslib a sufficient number of members who would be interested. Possibly the most telling point in our argument was the list which we compiled of aircraft firms who were not members of Aslib, but who might join because of the formation of the group.
