These photos were taken from the porch of a motel on highway 15 (Mojave Desert) our way to Grand Canyon in 2002. Finally these photos are explained. In a recent article on DailyMail UK titled, “There’s more to clouds than dull or grey and white and fluffy“, a very similar photo appeared with the following caption “Noctilucent clouds are crystals of ice hanging around 80km high in the atmosphere that catch the light of the sun long after it has set on the horizon. The cloud in this image was formed from the exhaust of a missile launched from a distant firing range.” We were indeed within range of a US army base. So the reason is likely to be identical in our photo.
