I hate when pax make such a huge fuss about things like this. The pilots landed the aircraft safe at JNB without any injuries or worries.
What about driving to and from the airport? Ever thought twice about the car infront suddenly coming to a stop! What goes through your mind then? Do you also tell the press about the fear you had? If you think of how many aircraft flies on a daily basis without any problem. Surely every now and then a engine will pick up a problem, or a pilot might have to turn back for safety reasons.
I give the Capt all the credit he deserves for turning back and making sure everybody arrives safe!
All the bumps and sounds-we all know how bumpy it gets this time of the year with the westerly winds.
If people are so affraid then take the bus! Flying is was and will always be the safest way of travel! (my humble oppinion)
