My first flight on a plane also happened to had a passenger have a medical problem. She had passed out briefly. The pilots had that plane turned around fast and paramedics were waiting at the gate. I'm just stunned they would still take off with a clearly injured passenger. And then not turn around after an hour into the flight!? They didn't want to land in India, but Hong Kong was only an hour away?
