Thanks for the complements and concerns.
As I have been travelling to Russia and Ukraine for more than 15 years, I am confident that I am well aware of the risks. I guess that everybody has his/her own definition about "acceptabel risk", so there is no point in discussing about that.
I've added 3 pictures of the last Su24 landing with the sun going down at Gvardeskoye. The next Su24 came in after sunset and they continued flying until at least 22:30.
With the sun
Smoke on

Enjoy.
