Interesting comments about Zimbabwe. SAA have been flying there for years. My first long haul flight was on an SAA 747 out of Harare, then Salisbury, on the way to London. It was during the worst of the 1970's tensions. (Some things never seem to change in Africa.)
Sadly the flow of people wanting to leave Zimbabwe is all too real. Given the fuel shortages, food shortages and genreal air of unease, I'd carefully consider which parts of Zimbabwe you'll be going to usnseallt82 if you are planning a trip. Even my family have advised me to reconsider a trip back to see them. Still the area around Victoria Falls is a lot safer.
I've often flown the Harare-Jo'burg route on SAA and the current schedules mean that the daily inbound BA
flight passes close to the outbound SAA flight. The pilots often point each other out.
