• There are no 777s in Ukraine
• In another topic you said you have to do with Lineage 2, which is an online multiplayer game. I doubt that an airline pilot has enough time to play such a game (neither my younger brothers do that...)
• It's called First Officer or Copilot, not "second pilot"
• Thanks to the extremely high resolution of the pic, you can clearly see the registration of the aircraft. It's N771UA, a United Airlines plane.
