Thanks Ray,
If dispassionate scientists were involved, then simple controlled observational experiments would be done to actually measure the effect. As aircraft get bigger the effect is likely to get larger. Of course most of the force of the engines goes into lift rather than forward thrust, in other words a downward and deepening effect on the stream it is flying through. An A380 at lift off weighs 550 tonnes, and if we assume an average weight of a transatlantic aircraft of 250 tonnes, with 2,500 crossing the Atlantic (for example) each day, it amounts to over 60,000 tonnes net downward force along the length of the stream being abused. It should not just be assumed that the effect is negligible. Time, surely, for some real data?
