F1,
I initially thought as you do...who cares and why would you want to do it anyway?!
Then it occurred to me that it would actually be easy to knock just one of the levers to the TOGA detent...a slip as a hostie passed a meal tray, someone stumbling as they tried to get into the seat etc.
If it was done unintentionally, as we have seen in the sim, apart from the FMA, the indications on the engines are quite symetrical so no obvious clues there. Main thing is that the autothrust is no longer active and the aircraft will accelerate towards Mmo and an overspeed.
Agreed not likely....but possible!
