Aircraft hijacking ( also known as skyjacking , plane jacking , air robbery , air piracy , or aircraft piracy , with the latter term being used within the special aircraft jurisdiction of the United States ) is the unlawful seizure of an aircraft by an individual or a group . Dating from the earliest of hijackings , most cases involve the pilot being forced to fly according to the hijackers demands . However , in rare cases , the hijackers have flown the aircraft themselves and used them in suicide attacks ; most notably in the September 11 attacks , and in several cases , planes have been seized by the official pilot or co-pilot
