The US Attorneys Office just issued the charge which include federal crime of interference with the performance and duties of a flight crew member or attendant.

The complaint and supporting affidavit allege that Johnson and a traveling companion
boarded Hawaiian Airlines Flight 39 on the morning of January 6, 2010, destined for Kahului, Hawaii. It is alleged that Johnson, after boarding the flight, became upset because he was not allowed to place his bag under his seat. It is further alleged that a short time later, Johnson handed a comment card to a flight attendant, who then gave the comment card to the lead flight attendant. Government documents say the lead flight attendant then gave the comment card to the Captain of Hawaiian Airlines flight 39. It is alleged that portions of the note contain language that includes “I thought I was going to die,” “I hope we don’t crash and burn,” and “what if the plane ripped apart in mid-flight and we plumited (sic) to earth…” The Captain read the card and locked the flight deck as a precaution. He told investigators he felt threatened by the contents of the card, especially when he considered Johnson’s earlier suspicious behavior with his bag. After speaking with the flight crew about the incident, the Captain decided to declare an emergency and return the aircraft to Portland
