Capot: Thanks for the information. Indeed what I call "Al Ain old airport" is just south of the Hilton, and seems to correspond to what you described. Buraimi airfield is north of it, 500m east of Buraimi fort. That is the one that brakedwell remembers using with his Twin Pins. He says there was no runway marked as such in 1960, but a choice of landing directions according to the wind, and where the Landrover with the beer was standing!
The runway at Al Ain was about 1800m before they dug it up in the last few weeks.
JW411: You are right. It is very different now, and it changes every day. I thought Daudi was what we now refer to as Buraimi, but I may be wrong. I hope to check it when I am there in April.
Thanks both
Laurence
