Brian Owens of Everett, WA, asks:

Scott Ledbetter, on Dec. 5th, wrote "The straight line distance between 2 points on a ball is not necessarily the shortest distance." Actually, the straight line on a ball IS the shortest route. However the distortion caused by converting a ball (the Earth) to a flat chart means that a straight line on the chart does not represent a true straight line on the earth. The "Great Circle Route" is a curved line on the CHART that represents a straight line on the EARTH.

Jim Leishman responds:
Brian, you're correct on this.
