Y'all might want to google on (meteorite hit person). It's happened before, and both the impact velocity and the surface temperature of the objects is much less than you seem to expect.

Small pieces would slow to terminal velocity after being in the earths atmosphere for a short period of time. Big pieces would overcome air resistance due to their mass and carry their enertia all the way down.
