How the run ended

Finished on its own with a passing video, contact sheet, route map and report, at no cost on OpenRouter’s free tier. The report claims more than the contact sheet shows: the first frames are empty sky, the camera is strongly tilted for most of the flight and the city is dark until the last seconds. Not judged yet.
