Dramatic clouds over Athens - extreme range flying at dusk

During a recent production a test flight yielded this relaxing video. Technical info: Distance was 7km one-way; we flew using a special antenna array. This way we were able to safely fly despite the 2.4GHz band being totally flooded by millions of WiFi devices. We did however not use amplifiers. The video is playing at ~150% speed to match the tune. Soundtrack by JCO/Still - taken from "Through the cracks"
