Polish national airline, LOT, cancelled 10 flights as a result of the airline’s ground computer systems at Warsaws Okecie airport being subject to attack by hackers. LOT’s ground systems were unavailable for 5 hours during which time 10 flights were cancelled impacting over 1,400 passengers. The FBI said a security researcher, Chris Roberts, hacked into the Inflight Entertainment Systems 15 to 20 times over a period of three years. American Airlines grounded dozens of its flights due to a software problem on the iPads issued by the airline to the pilots and co-pilots for viewing flight plans.”]
