No matter how much you plan and prepare, sometimes you just have to be very lucky.
I had my camera imaging The Moon and Jupiter occultation through my telescope at about 10 second intervals when I noticed the lights from a plane close to the moon. I realised that there was a chance that it would pass in front of the moon, so I quickly canceled the remote timer I was using to take the shots and instead started shooting high speed continuous frames. I managed to get this plane crossing the moon in five individual frames just as Jupiter was about to be occulted by The Moon.
This is a two image composite. The Moon, Jupiter and the plane are all one single image. I then took an overexposed image to bring up the Galilean Moons of (from left to right) Io, Callisto and Europa. Ganymede had already been occulted by The Moon.
