Big Sky

On another visit to the beach at Exmouth, I took my little drone for some different views.  On my first flight the thing started its return to home automatically as it had lost signal – very odd, as it was only a couple of hundred metres from me. So I landed and changed the battery (same level of charge) and the problem didn't recur.  I wondered if there was some sort of interference from the town's WiFi . . . or something.
