Mine was in the Orkney Islands in Northern Scotland with Papa Westray to Westray in a Norman-Britten Islander takes a couple of minutes, sometimes less. I took the flight because of that. I think it is the shortest scheduled flight in the world, or was.

There was a flight from Wings Field (LOM) near Philadelphia to PHL using Islanders and Trislanders that lasted about ten minutes. they've gone out of business, I think. I never took the flight but one of their pilots taught me to fly.
