When there's a medical emergency on a plane and the flight attendants ask if there's a doctor or nurse on board, they don't expect the U.S. Surgeon General to respond. But that's what happened on a Delta Airlines flight, with Surgeon General Jerome Adams tweeting yesterday (May 16th): "On my @Delta flight to Jackson, Mississippi (by way of Atlanta), and they asked if there was a Doctor on board to help with a medical emergency- why yes- yes there was. Patient doing well and like a good #USPHS officer, I was glad to be able to assist!" Delta said in a statement that Adams gave medical assistance when a passenger became ill before takeoff on a scheduled flight from Fort Lauderdale to Atlanta. Adams, who's an anesthesiologist, has been surgeon general since last September.
