When Boeing got around to including Wi-Fi capabilities in its aircraft, they had to determine how well the signals travel through cabins. Were there unexpected dead spots? And if so, could airlines pass these seats off on passengers they especially disliked? To find out, Boeing needed to run tests, and they needed to fill the seats in such a way that they simulated an actual occupied airplane.
The best way would be to get a bunch of people to sit in the seats during the tests, so signals could bounce around them just as happens when in flight. The problem with this, said Boeing, is that people get bored. The actual problem, Boeing neglected to mention, is that people have to get paid (remember, this is the manufacturer doing the testing, not an airline, so filling the plane with customers who pay for the privilege of being there wasn't an option). So in place of people, Boeing filled seats with something they considered the perfect substitute: sacks of potatoes.
Boeing proudly shared with the press their engineers' ingenuity, which is a little surprising. Not that there's seriously anything wrong with treating potatoes like people (a practice formally referred to as "anthropotatizing"). It's just that, till now, there's a good chance you've only ever heard the phrase "like a sack of potatoes" used when describing something handled roughly and callously, so you'd think they wouldn't want the public knowing that's how they think of people.
They used 10 tons of potatoes in each test flight -- with fifteen 10-pound sacks masquerading as each passenger, that adds up to about 130 potato people, which sounds about right. Afterward, they donated the potatoes to a food bank. Was this so they could use radiation-activated potatoes to control poor people's minds? The conspiracy balls say 'yes'!
