But anyway, Raft is one of the so-called Five Golden Dragons of the film's title and lands in HK in a helicopter at RAF Kai Tak.
RAF Kai Tak was the RAF base situated just north of the runway in Kowloon. It's been completely redeveloped now and there are a couple of housing estates on the old site including the Kai Yip Estate and Richland Gardens. There are still a couple of remnants left including the former HQ building at #50 Kwun Tong Road and on the opposite side of Kwun Tong Road, the former Officer's Mess - now the HKBU Academy for Visual Arts. I believe that's might be the distant building you can see behind George's head in the lower picture. There is also one of the Nissen huts left on the site which is now used by the Christian Action organisation.
In the top pictures you can see part of the original Choi Hung Estate at the back. That's Pik Hoi House and is still standing, along with the rest of the estate.
