I had previously attended a flight where the lower forward hold was supposed to be empty on arrival but when we opened it up we found that there was around 12,000kgs which were not offloaded at the previous station.
Pilots had already left the aircraft but I met them when they took the next airplane out and told them what happenned... I also asked if they noticed anything on the flight in but they said everything was normal. Looks like the holes in the cheese didn''t line up but I can imagine a different scenario with a heavier load, shorter runway etc.
Plane was an MD-11 from SHJ.
