Multiple glowing orbs taken above mountains in Slovenia

On October 26, 2013, a passenger of an airplane has photographed multiple bright orbs when aircraft flew over the small city of Bohinj, Slovenia. All these glowing UFOs were white and very luminous.

Witness statement:

I work as an airline pilot for an airline in Europe. In October 2013 I was operating crew member on the flight from Germany to Skopje (Macedonia). When we flew over Slovenia I decided to take some photos of the Triglav mountain and the Triglav national park. 

Only weeks later when I was looking at the photos I noticed several glowing orbs on 3 photos that were taken successively, one after the other. 

I never noticed the objects with my own eyes, however it is also true I never looked in that direction.
