Well, er, yes. Two aircraft flying at different altitudes. Surely you knew that? It's been explained oft times enough on ATS over the past few years and if you are interested in chemtrails you've surely read up on what contrails are, how and why they form and how atmospheric conditions vary from day to day and at different altitudes?
