Airbus thinks goose tip could trim fuel consumption

This story quacks me up!
There is nothing in the report about Wingtip Vortices that create turbulence.
Anyone remember the XB-70 crash ???????
If geese flew at >100 knots they wouldn't/couldn't fly in formation because of wake turbulence.
Airline travel of the future -super tight separation with full automation.
That is interesting: "Jet engines meanwhile produce a vortex that contains a flow of rising air". I was taught that the vortex (wake turbulence) was a byproduct of the wing producing lift. I knew the FAA had it wrong all along ;-) Nice job of fact-checking techxplore!
