The shape of the levers and the unlatching mechanism are indeed veeeery different.
Indeed and it is why Ihave a bit difficulties in accepting a simple lever mix up. In addition to what you said, the flaps is one lever, conditions are 2 , and as someone explained earlier there should be specific buttons to push of pull to go to feather. These facts combined with quite experienced pillots , which had done 3 evious flights on the same aircraft that day , almost CAVOK., no real stress or emergency , just a request for a QFU change , it does not really add up.. .I think we are missing something here.
