The shortest regularly-scheduled commercial flight in the world is operated by Scottish airline Loganair. It runs between the islands of Westray and Papa Westray in the Orkney Islands. The entire flight takes 80 seconds to cross less than two miles. This video is three times as long as the flight. Passengers don't even have time to get scared. But then again, the plane doesn't climb all that high and it doesn't go very fast, either, for an airline.
The flight is a lifeline for the fewer than 100 people who live on Papa Westray, because there is no bridge between the islands, and the ferry is quite time-consuming. It's almost like a city bus service. There's no mention of the airfare, so I went to Loganair's website and did not find this flight listed for advance reservations. I guess you have to be there, like getting on a bus. -via Digg
