Your plane flies much faster than a car, so the flight time is about 1/2th of the time it would take to drive. The straight line flight distance is 11 miles less than driving on roads, which means the driving distance is roughly 1.2x of the flight distance. 'as the crow flies' which is calculated using an iterative Shortest distance is actually the 'great circle' distance, or Because of the curvature of the Earth, the Now let's assume you have a private jet and you can fly in theįastest possible straight line between Rochester, Minnesota and
