Many years ago I bumped the tripod on my 8x10 view camera knocking it over. The camera survived, the lenshood was toast, the filter ring threads on the lens were clobbered, and the lens had a nasty internal crack for about a half inch near one side. Fortunately, the lens defect had no visible effect when stopped down.
Just a few years ago I thought I had attached my Pentax 67II to the tripod, but I hadn't inserted it into the quick-release correctly, and the camera landed on its head on the parking lot pavement. The expensive meter-pentaprism was damaged beyond repair, but the camera and lens survived intact.
I tripped and went down on top of my Mamiya 6, destroying the lens hood, which apparently absorbed the shock so the lans and camera were just fine.
I haven't had my first major accident with my 5D yet, but I'm trying to be careful.
Two of my view-camera shooting friends went out on a shoot once, and when they were about to go home, the driver backed his SUV over the other guy's camera (he thought it was already stowed.)
There are all sorts of ways we can keep the camera manufacturers in business.
