Masafi?
Nope, definitely not Seiq. It was much nastier. The strip was quite a bit north of Masafi and we called it Tayibah. Looking at the map, it was on the old Dibba to Kalba inland track. Like the Firq-Seiq task, we used to ferry stuff in from the much nicer strip at Manama - but very rarely because everything about the place was tight; the approach, the surface and the length of the strip.
