最近有兩起事故，劇情幾乎一模一樣。飛機起飛過程中，離地瞬間突然大角度滾轉，機翼觸碰地面或其他物體而受損。下面選擇其中一例，學幾句通話。
學習筆記：
1. Tower: American 300, wind 300 at 17, runway 31L at KE, cleared for takeoff.
Pilot: American 300, cleared for takeoff, 31L at KE
呼號American 300，雙方發音都是American three hundred
非全跑道起飛許可，以前見過用shortened，這裡又見到一個更具體的、給出道口的格式
2. Pilot: We had a strong roll to the left, and as we climbed out, we decided to return to Kennedy.
roll: 飛機沿縱軸橫滾，滾轉
我們（離地時）曾向左大角度滾轉。我們離場爬升時，決定返回甘迺迪。
3. Pilot: The airplane is fine right now. We'd just like to return to Kennedy and have him checked out.
指代飛機，要用him，不用it。have him checked out指讓別人檢查，而不是自己親自檢查
4. Pilot: We were banking, uncontrolled bank 45 degrees to the left and in the air...
bank坡度角或壓坡度
uncontrolled或uncommanded指由外力造成，不是飛行員操縱
5. Pilot: We had an uncommanded roll to the left as we rotated.
我們抬前輪時，飛機自己向左滾轉
看網上信息，飛機離地一剎那，突然橫滾45度，機翼削在跑道附近標記牌上。飛行員使用不同詞語來描述事情經過，下面總結幾個描述這個現象的句子：
We had an uncontrolled bank of 45 degrees to the left when we departed.
We had a strong uncommanded roll of 45 degrees to the left when we rotated.
We banked/ rolled 45 degrees to the left upon rotation.
至於這是什麼原因造成的，留給各位專業人士探討吧！
