Leg 4 UNNT UIII (Tolmachevo - Irkutsk)

Take off from rwy 25 in Tolmachevo with ATC support was smooth. Weather was nice. Time 1155Zulu. In my hometown Riga was still daytime, but in the middle of Russia it is already night. En route we have tailwind fro 15 to 8 kts. Our cruising altitude as in all previous legs is 25000ft.

Lightning during cruise.
