Thank you Mr Mac. I don't think that the A340 wing probably has any flexibility in it at all which explains why the aircraft is as automated as it is. Humans cannot be trusted to fly airbuses. Have you heard any stories of the A340 wings flexing alarmingly as the aircraft flies over the ascending heat waves from the Sahara Desert? You'd better know the name of the Prophet's mother if you ever ditch down there. Personally and as regards SAA and the kit they use, I'd far prefer KLM and the Boeing 777, which is a magnificent machine.
