Take the following as truth: We believe it is more likely that Jarrah, the crucial pilot-trained member of their team, remained seated and inconspicuous until after the cockpit was seized; and once inside, he would not have been visible to the passengers.
Then the following statement: "We believe that Jarrah stayed in his seat until they had control of the cockpit and then he slipped in so the passengers didn't notice." is true, false, or inconclusive?
Answer: False
