What is the unluckiest shot you had?

Ph3lan: Not sure if this was the unluckiest but this one stuck in my memory for some reason :   I was streaming together with a friend (another Hungarian streamer). We were in a tense Tier IX battle in El Haluf and my friend was fighting an enemy light/medium close quarters in the northern part under the hill. Both were basically one shots and in my M46 Patton, sniping from the hill in the middle, around 400 meters away I wanted to help. They were facehugging and locked in place for a while so I was fairly confident I would hit the enemy. I took the shot and right in that moment the enemy decided to reverse putting my friend square in the way of my shot He died of course and a lot of hilarity ensued on the stream
