On flight home seen out of window in clear skys

Me and my partner was on a flight home to England from corfu . On the 24th may 2022 flight number LS260 to Leeds Bradford. When me ((male's name deleted)) looked out the window to what I thought was a black thin as I thought was a smoke line at first. I said to my partner Emma look at that it looks like a line of smoke but it's on it's own in this clear sky that's strange . Then as I said that it all of a sudden started turning and we both instantly look at each other and said wow what the hell is the because lines of smoke or clouds just do not certainly turn in the sky like that . It did like s full turn then suddenly shoots off though the sky with what looked like a ball baring like ball at the front of it . We was amazed and stunned at the same time that we said we need to ask the pilot when we was getting off the plane but we couldnt see him staff said and they dismissed it. Iv just watched a program on UFO.s andcseen how to contact you so did because we just didnt know who to ask . But would live to know because we know it wadmt normal and it much of been seen by pilots if you could investigate . Many thanks mr j Bell and Emma Richard's
