You got it good. Midnight for me .Looks like 8am Eastern, so 5am for me. Boo.

Also isn’t the pressure on an area equal to the square of the area or something like that so with faster speed comes a lot more force against a much larger diameter airframe.
and they'll eventually test the whole thing with a big fireball.
Let's hope that's the only way.Maybe even intentionally!

Another reason to blow the booster. I mean seriously, how hard would it be to send the abort code?Even SpaceX is rooting for a fireball. They want the fuel to burn up, not land in the ocean.
You're very close! Force is equal to pressure times area and for subsonic travel (incompressible flow) dynamic pressure is equal to 1/2(air density)(velocity^2) In this case, yes pressure goes up exponentially with speed, and the dynamic forces (including drag!) go up severely as well
For supersonic flow (compressible) things get nastier and some folks ditch the term "dynamic pressure" for "Impact Pressure" which involves specific heat ratios, Mach number squared and other fun quantities
Launch a model rocket without the nosecone and even with fins you'll see why SpaceX doesn't expect the booster to survive.
But, there's a HUGE difference between "not surviving" and "erupting in an enormous fireball, out of which the capsule rockets away safely". I know which one I'd rather see.
