We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
I'd rather be on a flight with an EMS person than with a Dermatologist. Every person should know how to do CPR. The tricky part is knowing when it is needed. If they stop breathing and turn blue, probably yes.
People do die on airplanes, but they probably would have died anyway. Interesting factoid: airplane air has 10% lower oxygen than the air on the ground.
Over the years I seen a lot more sick people boarding planes. Not only the chronically ill or very frail elderly, but young and middle aged people with flue or very bad colds. Occasionally I've seen a flight attendant turn them away, but not often. Add the very pregnant and a big enough population of medically questionable passengers to start getting concerned. Unlike ground transport where at least you can stop the car in seconds, emergency landings of airliners are difficult and sometimes dangerous.
