>>8080946From memory, it's an abandoned airforce base hidden under a mountain somewhere in the former Yugoslavia; the runways above ground and parts of the underground base were rigged with mines/explosives to prevent the base falling into enemy hands during war, these mines/explosives were mostly removed after the base was abandoned, however there's a better than average risk some of the mines/explosives were missed during the clean-up and are/were still live both at the time of that video and possibly even still to this day.
This is why it's definitely not recommended to go randomly lurking about on/in that base in particular, or any other apparently abandoned military base anywhere in the world for that matter, like they did in that video - you just never know what nasty surprises were left behind.
