Buraimi
Thanks for the reply. Yes, Al Ain was just one part of the Buraimi oasis then. The strip you are referring to is the one near Buraimi Fort. It appears on various maps of the time.
The old Al Ain airport can be seen on Google Earth, further south and near the present Hilton Hotel.
I have seen a photo of a Twin Pioneer that landed there (or nearby - I am not sure) on a medical mission. It was shown to me by a very famous lady, Gertrude Dyck, named locally "Dr Latifa". I wonder if you ever came across her. She was one of Al Ain's first medics. Unfortunately I do not have a copy of it.
