At first teenage passenger Millard Kensington is suspected because he has a history with the airline as a known prankster who clogged a previous flight's toilets with 13 sponges he carried aboard. He is suspected of placing the fake bomb in the first class passenger lobby in New York is now on Flight 502. After confronting the teenager regarding the seriousness of his actions and getting him to admit he did place the fake bomb in the airline passenger lobby, he is nevertheless apparently clueless about the serious nature of the found letter. Realizing the teenager's lack of malice Captain Larkin demonstrates he too means no harm to the boy and successfully defuses the moment when he invites him to visit the cockpit later so he can show him "How this thing practically flies itself." which the boy cheerfully accepts. He then relays a message back to Davenport that he thinks this is a red herring and requests further detailed backgrounds on the passengers as he only has names and addresses to go on from the flight manifest.
