Back in 1979-82, I flew a helicopter in East Africa supporting missionary work - evangelism, remote medical clinics, famine relief, etc.
Swahili is the trade language of East Africa. ‘Ndege’ is the Swahili word for ‘bird’. ‘Bwana’ roughly means ‘Mister’. Thus, ‘BwanaNdege’ is “Mister Bird” .
One time while flying in a remote area of NW Kenya, I spotted a group of men carrying a woman on a makeshift stretcher. Upon landing I learned that they believed that she had broken her back in a fall. After getting her safely in the back of the helicopter, I told the men to continue on the the mission station. I would fly there, collect the nurse and take the injured woman to the closest hospital.
When the men arrived at the mission station, they reported that “Bwana was flying over in his ‘motor-car’, saw us, landed and has taken the woman to the hospital.”
Interesting origin of your handle. Thanks for the translation.
