Sure... www.PBS.org ; I saw it on a multi-part documentary on the
history of flight.

Well, I was recalling my old school days where we generally accepted
that the speed of sound was 1,000ft/s or 680mph. But you are right,
depending on altitude and air temperature it is between 700 and 800mph.

That's what I said, they fly by magic.

bboy_mn:
Someone once explained a theory that sounds very much like 'space
folding', but they used the example of a pleat (A fold in cloth made
by doubling the material upon itself). Although we, at that time were
talking more about physical space like Diagon Alley.

So this time/space-folding, am I right in assuming a 'pleat' would be
a good analogy? The span of time&space between two points is folded
back out of sight, thereby, creating the appearance that two points
are near by. This could be similar to a worm hole. The time and
distance through a worm hole is less that the time and distance
between the real points. In sense, the worm hole or time/space-fold
path is the distance between the two adjoining folds in the pleat, and
the real distance is all the 'material' that is hidden behind those
adjoining folds.

So you say a Thestral flys in real-time using a static warp bubble to
block the wind. I never said that wasn't possible, I even said it had
some merit. What I did say, is that while possible, I didn't
personally feel that it was likely. However, if my description of the
'time/space-fold' above is reasonably accurate, and that it is also a
reasonably likely explanation of Floo and Portkey travel, then I say,
it also explains the magical flight of Thestrals. As a Thestral flys,
it creates a turbulence in space/time, this turbulence in space/time
manifests itself as small folds in the surrounding space/time that
allow the Thestral to cover distance much faster that the perceive
real-time flighing speed.

Am I actually right? Well, we'll never know. It's just a thought. But
I am sticking to it. So ultimately, we'll just have to agree to disagree.

bboy_mn:
I'm pretty sure that I made a point of saying that what Apparation
feels and looks like is an unknown at this point in the book. 

I also pointed out advantages to your method; it's very simple and
straight forward. But it does have it's drawbacks, and I still think
there is information in the book (I gave examples), that leans the
likelihood toward my idea. And now that you have brought up
'space/time-folding', you have given me exactly what I was trying to
say, that perceived distance is not proportional to real distance. The
thing I describe as 'slow motion apparation' is simple traveling past
the magically created folds in space/time.

Really, it was just a thought.
