You guys are just idiots. Read the goddamned picture caption. Its a wing tip vortice research flight.Notice how the slats are extended so that the airplane flies slower . The smoke is generated so that the wingtip vortice can be measured, researched and then info can be given so that aircraft on takeoff and landing have proper seperation so that the trailing one doesn't end up rolling like a DERVISH.

We have real goddamned issues in the USA-our government is eroding our constitution daily. We are in a fucked up unwinnable war thats killing our military and costing us hundreds of billions of dollars. Odds are the government knew or even was involved in 911, and you guys are stuck on contrails. I am starting to hope they are real, because mental rejects like some of you shouldn't be allowed to bred.
