There was a classic at the Maldives, listed as a PAPI but was a T-VASI in fact.
One operator (ME) got REALLY low until a go-around was done.
Need to read their worldwide AIP! Although I will say that I never knew that in the US, if the PAPIs are flashing, it's a signal from some whizzbang system that you mustn't land (Rumours thread).
Don't worry Leddie, I won't be over there anytime soon!
