Sorry, but it wont be easier to simply "hijack" the truck or trucks with that supposed Money or Gold when driving towards Kuala Int Airport?
Ok, supposing an abandoned cold war era field along Kirgyz/China border was used....it was night period...no fullmoon light at all, poor Navaids or even some ATC, lots of High Terrain in prox, after landed some sort of heavy handling material with some (lets say) dozens of persons for staff that operation was requested, and another miriad of other questions too???
What doing with the PAX after that?
At least some runway working illumination, me thinks...after that where to hide it? Even nowadays sitting normally on our rooms we still surf the earth with Google Maps and Earth,,,its not impossible, but would say, too much Hollywood for almost failing 99%.
And too many people involved without one of them simply breaking the silence pact!???
