What is the carbon footprint of an aircraft Times A million?

Question

lets say a twin engine jet aircraft, flying at 35,000 feet, and a million of them in the sky at the same time. fact or fiction.

Answer 1

What kind of aircraft? A Cessna 150 or a Boeing 747? And how much does it fly? A Cessna 150 has a smaller footprint than many cars, but it only carries 2 people. A 747 has a giant footprint but it carries hundreds of people. A big footprint is OK if it has a big benefit. A bus has a much bigger footprint than a car, but most environmentalists say the bus is greener because it carries more people.

Answer 2

This is a really hard equasion to answer without having the value for A.  If you could provide that I might be able to help you out.
