Well done SB! I think you meant HMS Kipanga, which was the co-located naval air station, but Mombasa is spot on so take a bow.
I was actually after RAF
Port Reitz (named after the 19th century commissioner Lieutenant J.J. Reitz), now Moi International (after the former President of Kenya).
The airfield was established early during WW2 by the South African forces in preparation for the successful but little known conflict with Italy in the Horn of Africa. The airfield was home to Furies, Gladiators & Hurricanes, together with detachments from 12 Sqn and 34 Coastal Reconnaissance Flight, operating Junkers 86Z aircraft.
As an aside,19 Ju86 passenger aircraft were ordered by the allegedly pro-Nazi Defence Minister Oswald Pirow for South African Airways before the war, together with one Ju86K bomber, and the former were hurriedly converted for military use as war loomed. After SA decided to enter the war alongside Britain, the aircraft began coastal patrols in support of the RN base in Cape Town before some were moved to Kenya, where there was a further Ju86 base at Nanyuki.
The "French connection" noted in response to Jensdad's guess alluded to Ju86 ZS-ALN 650. In 1941 this aircraft became lost in a storm over Ethiopia and was forced to land in Djibouti, where the aircraft was impounded by the Vichy French and used as a transport with Junkers support, until returned to the SAAF in 1944 and broken up for spares. Apparently the use of German aircraft could cause confusion - on 31 Oct 1940, a Ju86 carrying the S.A. Prime Minister and C in C Gen.Jan Smuts and the British Commanding Officer East Africa, Gen.Alan Cunningham, was attacked and almost shot down by SAAF Furies based at Archers Post in northern Kenya after failing to give the required recognition signal.
The above mentioned SAAF unit emblems are visible in the crew room photo, including 3 Sqn's "Fighting Wasps."
'The Hurricane (I.D. letter is actually Q not O) pictured was from 3 Sqn SAAF.Following the move north by the South African units, the RAF base was shared during the war and after by the Royal Navy in support of carrier borne aircraft from the Indian Ocean fleet using Kilindini harbour.
The airport was extensively redeveloped in the 1970s, with a new runway. In addition to the activities as Kenya's second international airport, the base hosts air force units, including those pictured from the USAF - the C5s and C141s pictured in the early 1990s for relief operations "Provide Relief" and "Support Hope" in Somalia.
My sadly failed clues were: the repeated mention of "two rights" (=Reitz) and the words "magnificent" and "wonders" in connection with degrees East of Suez were intended to suggest the number "7" , which is the number of degrees that Port Reitz/Mombasa lies east of Suez. The"dependable engines" remark referred to the P&W Hornets on the SAA Ju 86s.
All yours, SB...
