for such a thing to happen when selecting toga you would not only have to ignore the flight director and the pitch attitude but the "to low terrain" egpws.
Forgive lowly SLF question here, but would the EGPWS messages sound if the thrust level didn't quite make it to the TOGA position, as was the case of the incident in Melbourne which someone linked? Would the additional thrust at this level be sufficient to create the conditions necessary for the illusion?
