Years ago in Cairns, the chutes were cleared to drop at Sugarworld (near Edmonton). The letter of agreement between ATC and the company required the pilot to visually identify the dropsite. Pilot reported chutes away, but he wasn't near Edmonton - seems he misidentified the Showground, with it's surrounding built up area, for the cane paddocks near Edmonton - or perhaps finger trouble with the GPS and couldn't see through the 8 OKTAS.
Chutes all landed OK, but unfortunately no arrivals or departures for 10 minutes due proximity to Cairns aerodrome.
