This is a plane for training student pilots. It’s been on display in the museum for decades. They attached something that look like bombs between the wings, but there’s no targeting mechanism.
There might not be an engine either (in the first plane). There doesn’t seem to be an exhaust.
My friend knowns one of the guys in the video — the one who climbed up the ladder and told the people not to touch anything.
And from this propaganda, Russia will begin saying it’s the LNR’s Air Force running sorties.
