The first time I paxed into Tioman in a Dash-7 it got my attention. Approach is up the bay, straight at the checkerboard on the lhs with a last moment hard right to the one-way strip, amongst the trees down low on the rhs of the photo. Missed approach ? I don't think so ! High ground to the left, right and centre. I'm sure the oil on the windows wasn't a lack of maintenance, it was carefully cultivated to stop the passengers seeing the approach.
