How high up in the air is he for that photo?
Edit:
You should be able to detect it from an aeroplane at a cruising height of around 10,600 metres (35,000 feet), but you need a fairly wide field of view (ie 60 degrees) and a virtually cloud-free horizon.
So he's gotta be at least that high to detect it at all.
