Seems like a quick advancing of throttles asking for take off flaps should verify TOWS working. Simple and flows with the initial taxi procedure. It would have saved all of those lives. In their case apparently no one asked for take off flaps so may have not worked. Interupted normal flow as they had can really mess up a routine. I always tried to start from scratch when an interuption of our normal routine made us backtrack on our checklist.
