I just took a flight out to the east coast to visit friends and my folks. I was fairly shocked to realize that none of the 3 airlines I was on recycled their aluminum cans. It may seem like a little thing to worry about, but according to the Bureau of Transportation Statistics, about 780 million people took a flight in 2007. In looking around the plane, it seemed that about 75% of passengers used an aluminum can. When they come around to collect trash, it would be super easy
