4 lights not recorded on camera.

At around 11:00 PM GMT, on the 08/12/2016, I was on my garden, doing some Astrophotography for the Perseid's meteor shower.  I was using an intervalometer so I could relax and enjoy the show.  
About half an hour into the session (So around 11:30 PM GMT), 4 Lights appeared from behind the tree line that was to the left of my vision.  My initial thought was it was a meteor, until I realised the speed at what it was travelling.  The distance it covered would have taken a meteor at a fast speed around 7-10 seconds.  This object covered it in roughly 3 seconds, maintaining its form of 4 Pin white lights that all stayed in equidistance of one another. 
Then it disappeared behind the line of houses to the right of my vision.  Thankfully, I had my camera trained on that area of sky.  After reviewing my images in lightroom (I had accidentally overexposed them by having my ISO too high), I saw that the camera had caught nothing.
