Here is a documentary about pilot flying 727s to remote area in Angola here is the description :

"Telling the remarkable story of the pilots who bring fuel to the remote diamond mines of Angola, Flying Tankers (Tankers en plein ciel) profiles João Amaral. Program describes how Amaral has spent the past 15 years making three daily runs to the mines with 17,000 liters of fuel in a decrepit Boeing 727, often in the gun-sights of various factions in Angolas civil war. Now,with the conflict over and infrastructure being restored, Amaral has exchanged his bullet-proof vest for an airline pilot uniform."
