Great job with the video and editing. Looks like an older fossil fuel (coal burning) electric genereating station. I just videoed the last plumes of vapor coming out of our TMI nuke plant before they decommissioned.
Nice video, very interesting.
If you had filmed the demolition itself with the drone near around like you filmed the coolers before they collapsed. that would be really something!
Was it forbbiden in the time of explosions or was forbbiden at all. If the last then you fly unlegally anyway.
