An object with a diameter of roughly 1.5km (which is very close to 1 mile) doesn't break up in the atmosphere. Considering that the vast majority of the atmosphere's mass is within the first 16 km, this object has a width just over 9% of the thickness of the most dense part of the atmosphere), and it's likely moving at tens of thousands of km per second. It would have punched right on through the atmosphere in no time, impacted the Earth, and ejected molten crust all over the place.
