此事不該因人廢言，不過這次"大佬"可能會踢到鐵板。
"大佬"有足夠的飛行經驗，但不代表他理解所有系統。
有些工程設計資料或邏輯是不會寫進飛行手冊或一般的維修手冊。
(這就有點像您是開某種車的多年老手，但您不見得會完全清楚該車的工程資訊)

如果"大佬"有參加過類似的失事調查經驗，他應該就不會如此"鐵口直斷"。

還有初步調查報告說：
"The aircraft achieved the maximum recorded airspeed of 180 Knots IAS at about 08:08:42 UTC and immediately thereafter, the Engine 1 and Engine 2 fuel cutoff switches transitioned from RUN to CUTOFF position one after another with a time gap of 01 sec."
但就有有經驗的飛行員說"Panicker says that it's almost impossible to transition switches for both engines manually within a matter of a second"

真的是同樣文句，卻有不同的理解。
所以，每個人看這份初步調查報告後，都可以構思自已的劇本。
