Making headlines yesterday, security researcher Chris Roberts is being investigated by the FBI for claiming the ability to mess with a plane's flight systems from onboard. An ill-received tweet started it all, as Roberts claimed he could hack his flight's oxygen regulation. Roberts went on to tell the FBI that he hacked en-route 15 to 20 times over the several years using his laptop, modified cables, and the in-flight entertainment systems. He even claimed to be able to access engine commands and make his plane move sideways. Industry experts are calling Roberts out on his claims, citing a range of reasons why his claims are dubious, if not impossible.
