    LEFTANGLE

    If you shot a projectile at this speed at a horizontal angle from your position, it would reach 5 miles in one second. At the same time, the projectile would fall towards the earth, 32 ft in one second. Now look at the curvature of the earth (roundness), five miles away, the ground is 32 ft lower. If you fired the projectile 5 foot off the ground, it would be five miles away in one second, it would have dropped 32 ft, so five miles away the ground is 32 ft lower, so the projectile is still 5 foot off the ground. It is in orbit! The problem with this is that air friction will slow it down.
