I was flying with my family from our vacation in Denmark back home to Prague when I saw some cool lights from my window so I filmed it. I thought that was it, but when we climbed above the clouds I saw that our plane's shadow is surrnounded by some halo/rainbow. As we climbed higher the halo slowly disappeared. I don't know if I uploded it right therefore sorry if there are multiple same videos. Love your videos. With love from Czech Republic Pavel.
