There is no Twin Otter, there is no Skyvan and the Dornier that they have has been grounded for 8+ years!
They jump every once in a while but like it has been said before, it is very expensive(U$ 35+ dollars)to 10000 Ff If the pilot feels like it! and they usually jump out of aircraft that is not really suitable for skydivng.
Take a lot of bug spray, otherwise, you get gang banged by all the mosquitos.
