Passengers landing at remote Ornskoldsvik Airport in northern Sweden might catch a glimpse of the control tower -- likely unaware there is nobody inside.
The dozen commercial planes landing there each day are instead watched by cameras, guided in by controllers viewing the video at another airport 90 miles away.
Ornskoldsvik is the first airport in the world to use such technology. Others in Europe are testing the idea, as is one airport in the United States.
