Take the following as truth: The hijackers probably did not know how to operate the cockpit radio communication system correctly, and thus inadvertently broadcast their message over the air traffic control channel instead of the cabin public-address channel.
Then the following statement: "The hijackers accidentally broadcast their message over the air traffic control channel instead of the cabin public-address channel, probably because they didn't know how to operate the cockpit radio correctly." is true, false, or inconclusive?
