As most of my family are from and are out there, my uncles who are local dignitaries have had the pleasure of visiting GFS, and it's predecessor RHKAAF over the decades.
Myself the last time I was in HK , it was the era of the S-70 and S76 used to see the go out a lot on missions. Also when I was a kid, remember the SA365Cs go out.
This year they're putting out a tender (I put this on another thread) for new aircraft and they should have had their new Challenger jets delivered by now

I've also had the pleasure of working with engineers who had a spell in the GFS as well in my old place.
Cheers
