Tanzania is interesting with it's huge amount of bush airports that get a decent amount of traffic from safaris and other local travelers. Trips that take 10 hours on the road can be done in a 45 minute flight.
Would be great to have thoughts / feedback from the HN Community. Also happy to chat in general if you're planning a safari trip :) Email is in my profile.
I've grown up in Tanzania and partially based in Kenya past few years and partially in California, I'm intimately familiar with the safari scene there. Spoiler - it's incredible.
The big reason for high wing bush planes is for ground clearance, and to avoid damage from debris kicked up by the wheels.
In general one wing wonders work better (and you even say some of the later biplanes not having wings right over each other).
