Thank you thank you thank you!!! It is so good to know that I haven't been imagining things for the past 40 years! I remember seeing the shuttle as I sat in class at school, but because no-one else saw it no-one ever believed me! My desk was next to the window and I'd just happened to look up at the right moment. I don't recall seeing the 747, but I definitely have a memory of the shuttle in the distance travelling South to North, and that it took a few minutes for it to sink in as to what I was seeing. Looking at google maps, it is perfectly feasible that I saw it passing over Leamington/Warwick and on to Birmingham that day. I was at that school (North Leamington Croft Hall) between 1981 and 1985 and the view was out to the West, so the flight path and June '83 sounds just right. Thank you all again for the confirmation!
