The Sakhir airport is no secret. 12,000 ft runway overlooked by the Hamad Town escarpment and next to the Formula One Circuit. Hangar big enough for anything but an A380. If you look on google earth you can see the old 6000 ft runway which is now a taxiway. No ICAO designator yet because it's private for the moment.
Big white crosses on both ends of the runway but an ILS calibrator was whizzing about a few months ago.
Sakhir? Shaik Isa? Jumble up the letters and you can take your pick. Believe it when you see it.
