You may have seen on the news that a Dutch chap claims to have flown under his own power from a standing start.
Watch the video...
I don't buy it - I think that...
those wings beat too quickly to generate enough lift (compare to the beat-rate of much smaller swans, eagles and condors)
the wing membranes don't show enough sign of being under load - they're too loose and flappy.
the wings look the same on the down- and up-strokes
the upstroke should push him down, because the membrane doesn't close up like a bat's wing, or let air through like a bird's wing.
In fact, I reckon he's on strings.
What do you think?
Thanks to those comments from The Usual Suspects - so it's a fake after all.
I ought to point out, as well, that the BBC had been reporting this on their website as well, but the story has mysteriously disappeared in the last few minutes (I didn't provide the BBC link, since most non-UK readers are able to see video on their site).
