Flight Radar: Antonov An-124-100 - who operates this?

[Pinesinthedunes]

Hello, just that really, lain in bed listening to the birds and I heard an unusual sound overhead, not like normal planes. Looked at flight Radar and it was an Antonov 124 from Bangor airport Maine, heading to Ukraine (I'm guessing? Still watching it). I thought only Russian military used those. Any ideas what this was?

They're Ukrainian planes.

They are used as cargo planes by Antonov airlines (Ukraine).

Thank you, wonder what they were transporting
