It happened to me twice in one day a couple of weeks ago, while attached to my 300 f/2.8 and using a Black Rapid RS-7. The first time I was taking it out of my rucksack, it detached itself, hit the end of the boot on the minibus we were travelling in, then landed back side down on gravel, so a relatively soft landing, but it did scratch the screen. The second time, I had checked it was connected five seconds earlier, but it still detached as soon as I let go. Luckily, it landed on the quick release plate and that took most of the force, taking a gouge out of it, plus a few scratches on the battery grip, no marks on the body. The day before, it had partly disconnected a couple of times and I only realised when the shutter didn't respond (luckily I was just checking exposure). Ironically, as soon as I attached the BR strap through the Canon one on the body, it didn't do it again, almost as if it knew . It seemed to be shooting fine afterwards, although I don't have any AFMA set on the MkIII, as I haven't seemed to need it (I also haven't got around to testing it).
