Should a south-african prosecutor ask a counterpart in France to seize from Airbus the ACARS of the 4 airplanes, is there a chance to prove that the 4 A/C were perfectly airworthy until they touched ground in Iran instead of Uzbekistan, as officialy planed?
If so, this could be the start of an indictment against the pilots and their employer for violating the sanctions against Iran.
All right, I'm a dreamer: I never heard of corruption in South Africa nor of its government very scarce interest for its own reputation.
