特に誤操作防止の赤い蓋とか透明な蓋とか大好物ですねー。
このへんはぐぐればいくらでも写真でてくるから大丈夫だろうということで、自分で撮った写真を！

I especially love red or transparent covers to prevent erroneous usage.

I've used the photo I took, since I Googled this part of it and tons of images came up, meaning it was okay! I.e., the helicopter's control panel isn't classified info.
