Suppose there was a race of aliens who had created engines for there spaceships that could operate at any speed under light, and Hulls strong enough to withstand the crushing pressure of earths core several magnitudes over along with heat. These aliens are very arrogant and do not care about physical restraints and often fly down to planets with their very un-aerodynamically shaped ships and travel at amazing speeds causing extreme drag on the ship, but their engines are so powerful and their hulls so strong that they give no notice to this and just proceed faster
What would be the impact of the surrounding area of (lets just say earth) if these aliens decided to fly past a city or a neighborhood with complete disregard of the hazardous effects of the atmospheric drag on their ships?
-Assume the ship is a 200 foot cube
-Assume that the ship is flying at about the height of 2722 feet or lower
-Assume the ship is a cube or an even more un-aerodynamic shape
-Assume that the ship is traveling at at least re-entry speed of the space shuttle, you can also assume they can travel at much greater speeds than that in the atmosphere
