Less than an hour afterward the Big Boss ordered the outfit to tune in ultrophones on three-twenty-three to pick up a translated broadcast of the Han intelligence office in Nu-yok from the Susquanna station. It was in the form of a public warning and news item, and read as follows: "This is Public Intelligence Office, Nu-yok, broadcasting warning to navigators of private ships, and news of public interest. The squadron of seven ships, which left Nu-yok this morning to investigate the recent destruction of the GK-984 in the Wyoming Valley, has been destroyed by a series of mysterious explosions similar to those which wrecked the GK-984. "The phones, viewplates, and all other signaling devices of five of the seven ships ceased operating suddenly at approximately the same moment, about seven-four-nine." (According to the Han system of reckoning time, seven and forty-nine one hundredths after midnight.) "After violent disturbances the location finders went out of operation. Electroactivity registers applied to the territory of the Wyoming Valley remain dead. "The Intelligence Office has no indication of the kind of disaster which overtook the squadron except certain evidences of explosive phenomena similar to those in the case of the GK-984, which recently went dead while beaming the valley in a systematic effort to wipe out the works and camps of the tribesmen. The Office considers, as obvious, the deduction that the tribesmen have developed a new, and as yet undetermined, technique of attack on airships, and has recommended to the Heaven-Born that immediate and unlimited authority be given the Navigation Intelligence Division to make an investigation of this technique and develop a defense against it. "In the meantime it urges that private navigators avoid this territory in particular, and in general hold as closely as possible to the official inter-city routes, which now are being patrolled by the entire force of the Military Office, which is beaming the routes generously to a width of ten miles. The Military Office reports that it is at present considering no retaliatory raids against the tribesmen. With the Navigation Intelligence Division, it holds that unless further evidence of the nature of the disaster is developed in the near future, the public interest will be better served, and at smaller cost of life, by a scientific research than by attempts at retaliation, which may bring destruction on all ships engaging therein. So unless further evidence actually is developed, or the Heaven-Born orders to the contrary, the Military will hold to a defensive policy. "Unofficial intimations from Lo-Tan are to the effect that the Heaven-Council has the matter under consideration. "The Navigation Intelligence Office permits the broadcast of the following condensation of its detailed observations:
