Hi Danny:
Thanks again for trying to keep the discussion on a "sane" level.
Re your question on the A320, there is no interlocking mechanism on the thrust levers like the Boeing system. So, if one were to select reverse on landing and then select TOGA thrust, nothing will stop the thrust levers from moving to TOGA. The thrust will be limited to idle by the FADEC as the reverser stows and then once stowed, the engine will accelerate to TOGA thrust.
You're right that doing so goes against the grain of normal airmanship thinking, but then again, as all too many accident reports have proven, if it can happen, it will happen eventually. While Airbus does not recommend a go-around after selection of thrust reverse, it "can" be done. If the crew really were in the process of attempting a go-around, then something else must have happened to perpetuate it, such as a loss of braking or a long touchdown. Only time, and a full investigation, will tell.
