Basic physics my friend. And googling will back me up.
research project that came to the conclusions above.
Care to post a link to it? I need a laugh.
You need a reality check.
Just for fun I did the calcs for your methane suggestion:
methane it atmosphere = roughly 1.8ppm
A commercial a jet engine takes in roughly 1 ton of air per second (going by
online figures) which for a high bypass turbofan means 100kg of air gets into
the compressor per second.
For a 10 hour flight that'll be 0.1 * 3600 * 10 = 3600 tons of air in
which there'll be 3660000 * .0000018 = 6.6 tons of methane.
Assuming all that methane gets burned (it won't but hey) thats equivalent
to about 165 tons of CO2.
A 747 uses 150,000 litres of kerosene on a 10 hour flight which will create
about 400 tons of CO2 which will be in the atmosphere on average for the next
10K years.
Therefor I think to sum up one can say nice idea, but no cigar.
