Sustainable Aviation

This is an interesting talk covering the ways in which aircraft design and operation could be changed so as to reduce the impact of aviation on global climate change. Turns out that it would most likely save gas as well. One interesting highlight is the fact that the average amount of gasoline used per passenger on a flight across the country from Seattle to Washington, DC is only 29 gallons. And that is taking into account the fact that on average an aircraft flies with empty seats!
