You might have noticed...the thread and story is not only NOT about believing the media report and initial version of the events, as reported, but actually highlighting HOW inaccurate it was vs. the visual evidence anyone could plainly see themselves.

I noticed that your claim was that the government provided faulty information. You didn't seem to consider that it was the media who screwed it up.

Winglets reduce wingtip vortices, the twin tornados formed by the difference between the pressure on the upper surface of an airplane's wing and that on the lower surface. High pressure on the lower surface creates a natural airflow that makes its way to the wingtip and curls upward around it. When flow around the wingtips streams out behind the airplane, a vortex is formed. These twisters represent an energy loss and are strong enough to flip airplanes that blunder into them.
Winglets produce an especially good performance boost for jets by reducing drag, and that reduction could translate into marginally higher cruise speed. But most operators take advantage of the drag reduction by throttling back to normal speed and pocketing the fuel savings.
Several airliners use them. The Airbus A319 and A320 have very small upper and lower winglets. The longer-range twin-engine A330 and four-engine A340 have conventional winglets, as do Boeing 747-400s. Aviation Partners, a Seattle, Washington company, has a new design it calls a "blended" winglet. The Boeing Business Jet (opposite, top), a derivative of the Boeing 737, has a set of the firm's eight-foot winglets with a curving transition from wing to winglet that is characteristic of the company's design.
