(NEWSER) – Capt. Mark Gongol flies B-1B bombers for the Air Force in his day job, and he had to put those skills to use while returning from vacation with his family on a United jet. About a half-hour into the flight from Des Moines to Denver, Gongol figured something was wrong when he noticed the engines idle as the plane made an unscheduled turn, explains Gizmodo. Flight attendants rushed to the cockpit, one with a first-aid kit, as the call went out asking if there was a doctor, then a pilot, aboard. "I looked at my wife and she looked back at me and she said, 'I think you should ring the call button,'" Gongol tellsCNN.
