If a pitot cover had been left on it should have been very obvious to the crew before they even got to 80kts on the take-off roll, surely?
Just like the Malaysia A330 on 18 July 2018 at Brisbane that became airborne with the covers on.
Which of course begs the questions...100 knots check? V1 Rotate? The crew acknowledged they had red SPEED flags on their PFD.
