I'm sure I mentioned windchill and wind turbulence. Haven't you ever
stuck your arm out of a car going 50 mph? OK... now multiply that by
10. Wind turbulence at 500mph would rip your head off. Pilots who
eject from their planes at that speed frequenlty sustain substantial
injuries from the sudden blast of 500 mph air.

Random:
Well, why can't _that_ be the magic bit? It's going 500mph _for 
real_  but maintains a bubble of static air around it.
Of course, i've seen anime with flying spells that explicitly create 
a bubble of air (slayers) so i'm biased towards that being the most 
believable explanation. However, it seems 

For the Thestral's case, where the body is not transmitted or 
teleported but actually physically transported, it makes more sense 
to just have a "bubble" of static air around the immediate area of 
the thestral.
 
Back to sticking your hand out the window of the car - it only 
happens when you stick your hand _out_, not when you first open the 
window. Even if you have the top down on a convertible, (at least in 
the front seat) you don't feel the _fast_ wind until you stick your 
hand up over the windshield. even with "open air" your car has an 
inertial "bubble" of air within it, and the magic could simply be an 
effect of creating that without the use of physical framework like a 
windshield.

Me:

Sorry, Random, that won't work.  Harry's eyes were "screwed up 
against the rushing wind."  His face felt "stiff and cold."  His 
mouth felt "dry and cold." (Us ed. pp. 765-766)  He definately felt 
a portion of the speed.  Wouldn't a static bubble have protected him 
from that?
