I believe you are correct. 250 below 10 is an ATC issue.
I seem to remember the 9 had a 5 layer windscreen, with 2 viynl layers, additionaly it was heated. Which in all gave it plenty of strength to withstand the "Frozen Chook Gun".
Likewise I do not recall TAA or Ansett ever having a problem in respect of windscreens and bird penetration.
If windscreen integrity was an issue it there would have been a Flight Manual limitation on the speed. There wasn't.
I agree with Wiley. I think
Centaurus has some serious social issues.
