Cash freight and fares in the jungle will always make money in a Twin Otter, just need to keep the operation safe enough to avoid accidents.
Used to be able to do likewise in 'brumm brumms' (otherwise now known as Bongo Vans) way back when.
Trouble is; From what I hear all the places I used to fly into, which for Douglas, Simbu, TNA, NCA etc were 'bread and butter' are now all closed!
Why is it so?
