US planemaker Boeing used an unusual substitute for passengers to test its in-flight wi-fi system - potatoes.
Passenger seats on a decommissioned plane were loaded with huge sacks of the tubers for several days as signal strengths were checked.
The company's researchers say that potatoes interact with electronic signals in a similar way to humans.

This lends a new meaning to the phrase couch potato.
So, how do you like your potatoes?
