I just had to releive myself
Doing refugee shuttles from one airstrip to another in PNG near the Irian Jaya border many years ago, I had my girlfriend along for the ride. THE ride.
We were empty on the back leg. What can possibly happen at 11,000 feet?
No autopilot. No worries. The front left seat of the Twin Otter has ample enough room for a nimble young one doing rear facing duties. There was a clean up garment required that was dutifully jettisoned into the jungle. Lucky PNG is sparsely populated.
