I would like to take this opportunity to express my heartfelt gratitude to you for your very active participation in our recent conference in Montreal on the “future of aviation”.The chairman and board members have also asked me to pass on their sincere appreciation for your efforts in supporting the institute in this important undertaking.
Your skill in chairing the controversial panel on “the role of developing countries in the future of aviation management” was highly appreciated by those representing all sides of that extremely sensitive topic.As well,we have received numerous post-conference requests for the paper you delivered on “the critical issue of cooperation between airlines and airports”.It appears that you my have penned a best-seller with that one!
On both a professional and a personal level,I really appreciated the time that the two of us were able to spend together for fun and reflection during conference down times.I certainly learned a lot about the unique aspects of aviation operation in your part of the world (not to mention the things you taught me about the backhand on the squash court!)
We are currently hard at work producing the “compendium of conference proceedings” document,and we expect to be sending it out to all participants early in the new year.
Again,thanks so much for your enthusiastic participation in our conference.I have no doubt that it would not have been the success without your presence.
