It's been a long time since I last photographed sunsets, but this was something different. On the flight from the UK to Hungary we had this scene, where it was hard to tell where the sun actually is. It was 14:50 local time, therefore the real sunset was hours ahead, yet the view was stunningly apocalyptic.
