I imagine we see a military kind of pilot training exercise here. It could also be the start of an invasion! Who knows :D I leave interpretation up to the viewer. The pic was created for the Luminarium Artgroup/Collective and its 26th exhibit with the topic 'Depth'. Created with Vue, Worldmachine, C4d & Photoshop - 6000px wide.
