This I.A.T.A. Symposium held during the I.A.T.A. Technical Conferences at Puerto Rico in April 1953 had as its object the free exchange of views and experience primarily between helicopter manufacturers and civil aircraft operators. The helicopter has been in operation for about ten years. The types available have, however, been in the main small, single‐engined military aircraft, but technical developments now promise fairly large, multi‐engined helicopters suitable for public transport operation. At this juncture, therefore, a conference of this nature is particularly valuable. Of course, definitive conclusions could not be reached, but the results of such a gathering of the most knowledgeable people concerned with helicopter design and operation cannot fail to be of the greatest interest.
