Just a thought but the behaviour of QF72 brought back to mind the Turkish A340 in the mid-Atlantic airprox of Oct 2000
Very interesting report
GobonaStick, thank you for bringing it up !
From what I can see, this event did not bring any important negative G, at least nothing close to what experienced QF72.
But it should be a report to be read by any bus pilot, and most importantly by any pilot riding close above an Airbus.
Strategic Lateral Offset over the NAT tracks seems to be a very wise move ... and Airbus "protections" should be studied and understood much more carefully by their operators.
