Short runway, gets shorter when wet.
Operated in/out of Georgetown for 6+ years in the B-707. As previously mentioned, the ILS was "intermittant", often going OTS in bad weather. Had the runway lights stolen ( copper $$ ) twice. So, security no so secure.
Short runway, often wet, ILS untrustworthy, lighting probably works, in a very black hole in the jungle. Fun times.
I have to say though, I worked with some of the nicest, giving people I ever knew ( Guyanese ).
