Air Travel in Africa: 1936

>> My guess is that the photo is from a landing in Kenya.

I thought the same thing too.

The fezzes show that it is probably in eastern or western Africa, in a country with Islamic influences.

Were the fezzes on the ground crew the tipoff?

...of an H.Ryder Haggard novel.

Something like "Miller's head was pounding, his stomach still roiling from the copious amount of Gin and Tonics he had consumed the night before. Still, he had the map, that's all that mattered. "Nothing like treasure to settle a mans resolve." he muttered, flicking his Rothmans into the Kenyan dust as he entered the oven that was the Handley. "Sooner we get this crate up the sooner we'll cool off." Miller mumbled to no one in particular as he plopped himself into the wicker seat. It was then that he noticed the scorpion crawling towards him.

My guess is that the photo is from a landing in Kenya.

The little bit of research I've done quickly says that Imperial/BOAC employed these planes on the imperial routes to its colonies.

The extent of England's colonies in Africa was:
Ghana
Nigeria
Somalia
Sierra Leone
Tanganyika and Zanzibar (later, Tanzania)
Uganda
Kenya
Gambia
Lesotho
Swaziland

According to the Century of Flight site, this is a Handley Page HP.42 Heracles. First put in to service with Imperial Airlines (later BOAC) in 1931. Held 38 passengers and a cruising speed of only 100 mph.
