My company had a carbon footprint analysis tool up for along time, that's about what we got out of it. Can't find it now, but I'm sure you can google it. I don't think you realize how bad jet fuel is and how much is burned on a single flight...I have no idea where you came up with that statistic, but it's ludicrous. Of course driving is a better thing than flying per passenger IF you carpool, but it's not like flying is that much more destructive to the environment than driving. The only way that statistic works in my opinion would be if I were the only person on the commercial jet and you had like 10 people in your car and we did the same trip.
