Cloud travel was influenced by three winds. (28.65 km) The low-altitude portion moved toward the west, the middle portion moved east-northeast, and the mushroom cap is believed to have moved to the north and west. None of the cloud-tracking aircraft made contact with fallout from the cloud mushroom cap (Reference 16, Tab N, p. CONTAMINATION. 33). The Wilson 2 and Wilson 3 flights, in the air until about H+13, detected no contamination moving toward Enewetak or Ujelang, and at H+15 Wilson 2 proceeded to monitor the upwind sector of the pattern. ingly, PC-1546 was ordered to move south out of the area and return to BiKini. An early report (H+3) from a sampling aircraft indicated an aerial reading in the roentgen-per-hour range 10 nmi 290 (18.5 km) south of the shot amen Wilson 2 noted low-level contamination in the vicinity of Rongelap; accord-
