Hi guys,
I was over Pakistan near position shano. I saw the huge light lasting a few seconds followed by an explosion. It wasn't a fire explosion, it was a florescence explosion that produced a huge sphere that got bigger&bigger. It also produced a cylindrical shape cloud that had a hole in the middle. It was travelling horizontally towards us.
I took a video and some pics of the cloud but it's not very clear.
I've never seen anything like this in my 19yr flying!!!
Could it be a nuclear blast in sky?! I hope not coz the radiation from such a blast would have catastrophic effect on us who were so close to it.
