Not incredible at all, but on a flight we took from Brisbane to Auckland a while ago, one of the last pax to board was an elderly lady.
The poor dear tripped and broke her leg somewhere on the airbridge, and, of course, couldn't fly.
We were sitting up front, on the left, and watched them remove, one at a time, and search the contents of about 7 containers before they finally located her luggage about an hour later. (2 items, each in different containers. No luggage tracking, evidently.)
I don't think anybody minded at all. Hope she was OK.
