Here we have an example of how the digital eye of the camera is more exact than the human eye. The camera caught what the photographer didn't even see at the time. Thats understandable since the iPhone screen is a bit small. There is only two reasons to stop by such a famous building as The Shard. One, to drop some aliens off (looking like us) to look around and do shopping. Two...to observe a marvel of the modern age...the building itself.

Eyewitness states: 

I was at Borough Market, near Cathedral Street, London UK, taking photographs of the top of the nearby building,The Shard. On closer inspection of the photographs, I noticed that a progressive path of unidentified objects was recorded on the several images that were taken. They were clearly visible above the pinnacle of The Shard. The time was approximately 4.30pm. In extreme close-up, the object to the far right has a clearer structure - perhaps metallic. I was using an i-phone 6 – I’m almost certain that these are not internal light reflections; I take lots of photographs and have never observed this phenomenon before or since.
