"Our copilot." He pointed toward a large liquid crystal screen at the far end of the cabin, now blank. "I want to try and use her to override Flight Control for the rest of the sequence."

"Petra, report countdown status."

"Affirmative," he answered back. "You will now initiate ignition sequence. Bypass remaining countdown procedure."

That is an override command. Please give authorization code.”

"Code P-18. Systems emergency."
