魔鬼在細節裏。 央視沒提供細節， 不說明任何問題。
隱身機平時采用不隱身模式飛行是讓你發現， 避免幫你的忙測試發現隱身機的方法。如果美軍在公海例行飛行也采用隱身模式， 那潛在敵人就有機會試驗各種反隱身技術。
反隱身技術將來總有一天會開發出來， 但美軍不會幫你的忙。
As a matter of fact the vast majority of F-35 sorties are flown without stealth active. This is done by putting reflectors on the plane that send back an image on radar. The pilot can also generate electromagnetic signals that allow both military and commercial radars to pick-up and track the plane.
The main reason for not using stealth is so that potential enemies over time will develop an expectation of seeing a particular radar return pattern that they will come to identify as an F-35… and that’s what they will be looking-for. When the plane has to fly a mission that requires stealth, the reflectors are taken off and signal discipline is maintained and the odds of the plane being detected drop to near zero.
When you hear people say they can detect F-35s, the chances are they are detecting them with the reflectors out, and they don’t realise they cannot detect them when the plane is being flown in stealth mode.

事實上，絕大多數F-35戰機的飛行都是在沒有隱身狀態下進行的。這是通過在飛機上安裝反射器將圖像傳回雷達來實現的。飛行員還可以發出電磁信號，使軍用和商用雷達都能探測到並跟蹤飛機。
不使用隱身技術的主要原因是，隨著時間的推移，潛在的敵人會形成一種預期，認為特定的雷達回波模式會被識別為F-35……而這正是他們要尋找的。當飛機必須執行需要隱身的任務時，反射器就會被取下，信號規則也會得到維持，飛機被發現的概率就會降到接近零。
當你聽到人們說他們可以探測到 F-35 時，他們是在反射器處於伸出狀態時探測到的，而他們沒有意識到當飛機處於隱身模式時他們無法探測到它們。
