Here's some of the text (and photos from the report):

The flapper, as it's affectionately known, sustained flight over about a third of a kilometre for 14 seconds at about 10:20 a.m. before being hit by a crosswind and almost flipping over, damaging the nose and front wheel on the runway at Downsview Park.

Wahoo. I'm away. Into the record books for me... :O

It's one thing to act like a bird, and another thing to think like a bird. Those who hang out a lot at airports know that airport birds look at the windsock before taking off.

The next thing that they look for is the guy with the shotgun.

Does point to a major problem though. Birds rely on active stability, same as we do walking. This design constantly varies it's dihedral, so would be tricky even into wind.
