Nathan Jones, 19, was aboard Alaska Airlines Flight 322 from San Diego to Dulles International Airport on March 3. Investigators found among the 19-year-old's belongings "multiple notebooks with texts that described how to operate an airplane, including takeoff, flight and landing techniques," according to court documents.
Jones has been charged with alleged interference with a flight crew, which carries a maximum penalty of 20 years in prison. The flight landed safely and the FAA is investigating, the agency added.
