A spaceplane is expected to land on a runway located at (0,0,0). The radar tracks it at (-2000,-1000,100). Assume x points east, y points north and z points up, units are kilometers, and objects move at linear paths on this coordinate system. An airplane is flying from airport located at (-100,0) to another at (100,100) and is expected to fly at an altitude of 5 km. If the airspace needs to be clear for 10 km around the spaceplane's projected landing path, can both flights proceed?
