A UN Mi-26 Halo heavy lift helicopter at the airstrip in Doro, Upper Nile State, South Sudan.

The Mi-26 is the largest production helicopter in the world, capable of even carrying a CH47 Chinook, albeit as an underslung load. It was originally designed to transport Soviet ballistic missiles into the Russian wilderness, where they could be hidden from NATO spy planes and satellites.

In South Sudan they are used by UNMISS - often for humanitarian purposes - to carry unusually large or heavy loads, such as earthmoving equipment for road or runway construction.

I have now spent a total of three days making a reportage of the Doro clinic and have thus far seen a wide variety of illnesses, afflictions and injuries.

These have included but are not limited to: numerous cases of malaria; one of pneumonia; a boy who tragically died of tetanus; and a six year girl who was butted into a fire by a goat - suffering severe burns to both hands - who was unable to reach the clinic for three days due to flooding in the surrounding villages.

A UN Mi-8 MTV-1 Hip helicopter lands at the Doro airstrip, Doro, Upper Nile State, South Sudan.

The pilot aborted his first attempt at landing due to brown out conditions and made another circuit of the airstrip before approaching from a different direction to minimise the amount of dust thrown up by the helicopter’s down draught.

This gave me enough time to get into position, as I rushed out of the nearby health clinic, to capture a shot of the aircraft on final approach and then landing.

Tomorrow morning I return to South Sudan after over two months recuperating from sickness in Nairobi. Physically, I am still pretty weak after only regaining five of the thirty pounds I lost while in Malakal in May and June. Emotionally, I am pretty exhausted after a number of false starts for my return and the stress from being so sick for so long. I return not by my own strength – as I have very little left – but with whatever strength the Lord empowers me with through his grace. So that through my own human weakness, His divine power will be displayed.

But he said to me, ‘My grace is sufficient for you, for my power is made perfect in weakness.’ Therefore I will boast all the more gladly about my weaknesses, so that Christ’s power may rest on me. 2 Corinthians 12:9

The final day of a VBS (Vacation Bible School) week at Joy Springs Church and Education Centre in the Kibera slum, Nairobi, Kenya.

At the end of August I joined a small team of missionaries from SIM Kenya at a VBS week in Kibera. During the week we led a Bible Study class and assisted in an art class, games and music.

It was the first time I have ever done anything like this and it was well outside of my comfort zone, but I was really glad of the experience and I learned a lot from it.
