Given the threat of Swine Flu, we were expecting some kind of medical encounter when we landed in Shanghai. This turned out to take the form of enviro-suited technicians taking each of our temperatures via a medium-range thermal detection device. If your forehead was too ‘hot’, you got your temperature taken with a digital mouth thermometer. Since we knew that a flu-sufferer within 3 seat rows could potentially mean quarantine, we were all happy that nobody on the flight triggered any kind of alarm.
