Boeing Uses 20,000 Lbs. of Potatoes To Check Aircraft Wireless Network Signals

coondoggie writes "Boeing calls it Project SPUDS — or rather, Synthetic Personnel Using Dielectric Substitution — that is, using sacks of potatoes perched on aircraft seats to test the effectiveness of wireless signals in an airliner cabin. Boeing said it was researching an advanced way to test wireless signals in airplanes and needed a way to effectively simulate 200-300 people sitting in seats throughout the aircraft."
