The air bit my fingers as I held onto the metal handle of my turnstile antenna in the pool of darkness that is Hackney Downs at night. A police siren rang out in the distance and a high-speed chase progressed, two police cars tailing another car around two sides of the park. Suddenly a faint neon light appeared to bounce and leap toward me, revealing itself to be a small bulldog wearing a glow-in-the-dark collar. NOAA-15 circled overhead, scanning the outlines of North Africa, Italy and Croatia until I lost the transmission in the blurriness of the Arctic.
