The photo below shows my Canon 5D's mirror.
Of course, it is most usefully to be found within the camera. However, this morning when out on a little expedition, the usual shutter noise was followed by an ugly death rattle. To my relief, when opened up, the mirror was just sitting inside the body, so hopefully no real damage has been done.
Thankfully, this 5D Mirror Detachment is a known issue and I can get it fixed for free. Hopefully it won't take too long...
