FBI: Hacker claimed to have taken over flight's engine controls

(CNN) A cybersecurity consultant told the FBI he hacked into computer systems aboard airliners up to 20 times and managed to control an aircraft engine during a flight, according to federal court documents.

Chris Roberts was detained by the FBI in April following a United Airlines flight to Syracuse, New York, after officials saw Twitter posts he made discussing hacking into the plane he was traveling on.

An FBI search warrant application filed in the U.S. District Court for the Northern District of New York describes the investigation of Roberts for possible computer crimes.
