The witness / photographer was traveling between Paris and Amsterdam on Thalys train. He tells us:
I did some checks with my camera in order to see if it was all right. Back to home, I downloaded the pictures on my computer, and I noticed an unknown phenomena on two pictures.
My first reaction was to consider that it was the reflection of the light of the cabin on the windscreen, but now I am not so affirmative. I would like to have your feedback about that.
The two photographs were taken on 11-05-06 at 14h05 in an interval of probably less than 30 seconds. It was over Belgium country.
Best regards
