Correction,
The onshore operator is Hornbill Skyways (not Hornbill Helicopters). They have had a number of accidents in the last couple of years, mostly I think due to a very old fleet of Jet Rangers (this is only my opinnion).
If you have an engine failure out in the jungle (or rainforest) you are in big trubbles. The trees are very very tall and very dense and the terrain uneven (ridges). It's almost impossible to walk true the jungle and it's so dense that you will almost not see the sun...
I think the trick is to fly along rivers (highways in the jungle) and then somebody might have a chance to find you in case of an emergency landing. Ofcourse, if you can make it without ending up as a crocodile lunch...
