I saw this on the internet:

"An Australian airline Qantas Airbus A330-300, suffered "a sudden change of altitude" on Tuesday. "The mid-air incident resulted in injuries to 74 people, with 51 of them treated by three hospitals in Perth for fractures, lacerations and suspected spinal injuries when the flight bound from Singapore to Perth had a dramatic drop in altitude that hurled passengers around the cabin." Now it seems Qantas is seeking to blame interference from passenger electronics, and it's not the first time; "In July, a passenger clicking on a wireless mouse mid-flight was blamed for causing a Qantas jet to be thrown off course". Is there any precedent for wireless electronics interfering with aircraft systems? Interfering with navigation instruments is one thing, but causing changes in the 'elevator control system' — I would be quite worried if I thought the aircraft could be flown with a bluetooth mouse."
