Longer flights to curb vapour trails

Any thoughts or observations on this news article from BBC this morning.

BBC News - Longer flights 'could curb impact of vapour trails' (http://www.bbc.co.uk/news/science-environment-27907399)

I say totally impractical! Even if it were possible meteorologically, think of the effect on the NAT system.

The article proves that any crackpot can get published if they put "as it relates to global warming" somewhere in the paper.

Besides, everyone knows they are chemtrails, just stop spraying.

EDIT: In the 70's they used to say that the contrails shaded the suns rays and caused global cooling...

EDIT 2: When aircraft were grounded from 911..dammit more facts

"Another study that took advantage of the grounding gave striking evidence of what contrails can do. David Travis of the University of Wisconsin-Whitewater and two colleagues measured the difference, over those three contrail-free days, between the highest daytime temperature and the lowest nighttime temperature across the continental U.S. They compared those data with the average range in day-night temperatures for the period 1971-2000, again across the contiguous 48 states. Travis's team discovered that from roughly midday September 11 to midday September 14, the days had become warmer and the nights cooler, with the overall range greater by about two degrees Fahrenheit."

And at one time the scientists of the day said the earth was flat!!!!

That's the biggest load of non-scientific nonsense I've ever read!

"We believe it is important for scientists to assess the overall impact of aviation and the robustness of any proposed mitigation measures in order to inform policy decisions. Our work is one step along this road."

Translated....... "our funding is running out and we need to justify your keeping us employed on more really important research"
