An empty airport, a lot of time and you
My question is, would you really need to wait until after hours to film that? Some of those concourses are pretty empty all day long. I once asked for ideas to give the airport on what to do with the underutilized space. I say fill one of the gates up with buoyancy neutral helium balloons for a big interactive art display. Call it the Warhol Museum West or something. Seriously, there ought to be some creative uses for some of that space out there.
