as the sound of a distant helicopter could just be heard above the background hum of the crowd , it seemed like just one more sign to martin , that he was in the right place : he would preach his message of higher we ; he would give the same speech that he had given that day , more than a year before , on top of the wendelson building to garnet wendelson himself ; the arrival of the helicopter in their midst would be like a spiritual visitation , a visual representation of his words .
