（案例分析）某航CRJ900在进近过程中，高度30英尺，突然跑道上闯入另外一架飞机，机组决定复飞，副驾驶操纵飞机，机长立即收到襟翼8度，造成飞机突然下沉接地，副驾驶此刻加油门至复飞推力，开始增加姿态复飞，造成机尾擦地。请分析以上机组执行任务复飞动作是否正确以及可能造成擦机尾的原因。(Case analysis) During the approach of one Airline＇s CRJ900 , at 30ft，there＇s suddenly another aircraft incursion the runway, the crew decided to go-around, the copilot took control of the aircraft, and the captain immediately retracted flaps to 8, causing the aircraft suddenly sinking to touch the ground. The copilot advanced the thrust to T0/GA at this moment and started to increase the go-around attitude, causing the tail strike.
Please analyze whether the flight crews perform the go-around maneuver correctly and the reasons that might cause the tail strike.
