| I walked among the fireworks and the celebrating masses on Tahrir Square as F16 fighter jets drew contrail hearts in the sky, and I felt sick. |
| It's hard to make a smoke plume look more threatening than a far-off contrail. |
| There was no contrail and the disc appeared to be at an altitude of 20 to 25 thousand feet. |
| The sun was only six degrees high in the south and was shining on the unusually short contrail giving the appearance of a shiny disc. |
| Between the horizon and the red contrail of an aircraft, the dying sun illuminates a scratch in the heavens. |
| These are not the greatest quality however they show in my mind the differences between a contrail and a chemtrail. |
