Given 'The flight had taken off just as American 11 was being hijacked, and at 8:42 the United 175 flight crew completed their report on a suspicious transmission overheard from another plane (which turned out to have been Flight 11) just after takeoff.', does 'The aircrew knew that there was something suspicious.' exist in a neutral realm, neither confirming nor denying the premise?
