I'm afraid that I've no retained logs or charts from back then with which to state authoritatively - but there was certainly a dogleg after Djibouti before setting course south down into Kenya, towards Wajir. I have Dire Dawa in mind from Djibouti, then a left turn to the airstrip (and NDB??) at Jijiga, before the turn south. I think the intention must have been to stay clear of Somali airspace, and that Dire Dawa was a visual pinpoint by day and a Doppler guess by night. And, indeed, no pyramids.
