SRT....
You make it sound as though we have a choice....
It's common for us to fly 800 nm over the rain-forest to a dirt strip with no alternate on arrival for maybe 250 miles and no comms with the destination...... Of course there's no weather reporting.... As for forecasting....how does anyone forecast where a huge Wx system will develop that might blank out a 1000 square miles of territory with Cb activity ? It's not like fog, widespread and relatively consistent. To have absolutey no way through is not common but it can happen...Nobody will pay for the aircraft to fly around almost empty except for fuel...
DRC has almost no aviation infrastructure yet aviation is the primary means of transport..The country is the size of western Europe but with only a handful of manned airports, fewer than that with runway lighting.....It can be very demanding and at times, lethal.
