جهاز الامن يكشف عن مؤامره خطيره !!واطالب بترقية قوش!!!!

Quote: The helicopter, with its ability to hover, will keep below that level so its instrument package can take readings. The instruments will be mounted on the helicopter on a long pole called a “stinger.” The instruments will then probe the earth using magnetic fields that react to minerals in the ground. The data is then used to construct an underground picture of the geological structure Grauch wants to study.
