As a physician who travels quite a lot, I spend a lot of time on planes listening for that dreaded “Is there a doctor on board?” announcement. I’ve been 71 only once – for a woman who had merely fainted. But the 72 made me quite curious about how 73 this kind of thing happens.

Things are getting better on the in-flight-emergency front. Thanks to more recent legislation, flights with at 90 one attendant are starting to install emergency medical kits to treat heart attacks
