我哋需要以特殊嘅傾斜角度飛行 來進行測量 所以聘請咗軍事飛行員 同測試飛行員來操作飛機 我哋需要獲得特殊飛行許可 當環繞呢啲山谷彎位飛行時 重力可達 2G
We need to fly at a special angle of inclination to take measurements, so we hire military pilots and test pilots to operate the aircraft, and we need to get special flight permits, and when flying around these valley bends, the gravity can reach 2G
