When I accepted the invitation, to speak at this meeting on “Some Outstanding Developments and Activities” it was presumed that in preparing this paper, it would be possible for me to make a selective use of information presented at our IVth International Agricultural Aviation Congress held in August 1969 in Canada. Unfortunately this is not possible. Therefore, I am unable to pass on to you a comprehensive summary of the interesting technical details of various congress papers. So, I have to take the risk, when addressing you, of spoiling my reputation.

These reservations being made, I would like to give you some facts regarding the IVth International Agricultural Aviation Congress of August 1969. The registered participation was 259 (35% of this number from the host country). It was therefore sufficiently international, although the participation from Asia and Africa was very small indeed.
