Nothing too remarkable about tonight's #sunset. I just happen to like the three parallel #contrails. We live under two orthogonal #airways here, one running north-south and the other east-west. The latter is usually busier as it includes transatlantic air traffic.

“Don’t Fear the Reaper”, the fuel jettison value for an Su27 is BETWEEN the engines. Fuel is NOT jettisoned directly from the engines themselves, not that a fighter aircraft in intercept mode would not jettison fuel to improve handling in the air.
What you really see is just an Su27 climbing behind the drone. As it climbs, hot gas from its engines reacts with cold air and forms contrails. All very normal.
Interesting. At around #sunset, the #contrails of passenger #aeroplanes glows very brightly and is visible from very far out. I spotted an #airliner near the #horizon which was heading this way and very roughly measured the time it took to pass by. That was around 15 minutes. Assuming that it was cruising at about 1000 km/h, it means that I must have spotted it about 250 km in the distance! Even if my timing was grossly overestimated at it was a mere 10 minutes, that still means I saw it around 170 km away when I first spotted it.
Above us are two #AirCorridors, one running #East-West and the other #North-South. At #sunset the #contrails are illuminated by the low #Sun and it makes them look brilliant.
The sunset itself was colourful at the moment I caught it.
