Your given figure of 810 m/sec (??) = 1574 knots (??)

The 91 m/s is CAS, use his one:

To convert to TAS (810 m/s).
Lower than this speed and it'll stall. And at the same time, the object is already far above the speed of sound. It won't fly, effectively just drop to earth, where the wings do have some (only a little bit) to control where it goes, IE the aspect of coffin corner.
Speaking about the space shuttle, I think, any object not designed from pure titanium will just start to glow/burn due to the friction (though, I never tested this).
Or, as
Xhorst and
TURIN write, your object will be shattered at that altitude/speed.
