I am sure that their superior British engineering can come up with power 
to over come  nearly double the drag to go from 762 to 1000 mph ( 
caveat...area needs to be considered).  Transonic drag is gonna bee a 
bugger to overcome. Ever see a transonic drag vs speed curve?  Now if 
drag is nearly double and it is likely to be way way more then increased 
thrust needs will be significant. I am sure they can do it, however.  I 
wonder how they are going to over coming rolling resistance?  That also 
goes up as some power function of speed.  Going to be interesting for 
sure.  I hope they can keep all the tires on the ground as they set the 
record. Some manner of objective evidence for that needs to be developed 
as teh shock wave is going to in all likely  obliterate the track marks 
from the wheels.

When are they going to make the first runs and attempt?
