About this route:
A direct, nonstop flight between Roscommon County - Blodgett Memorial Airport (HTL), Houghton Lake, Michigan, United States and Ivato International Airport (TNR), Antananarivo, Madagascar would travel a Great Circle distance of 9,176 miles (or 14,767 kilometers).
A Great Circle is the shortest distance between 2 points on a sphere. Because most world maps are flat (but the Earth is round), the route of the shortest distance between 2 points on the Earth will often appear curved when viewed on a flat map, especially for long distances. If you were to simply draw a straight line on a flat map and measure a very long distance, it would likely be much further than if you were to lay a string between those two points on a globe. Because of the large distance between Roscommon County - Blodgett Memorial Airport and Ivato International Airport, the route shown on this map most likely appears curved because of this reason.
Try it at home! Get a globe and tightly lay a string between Roscommon County - Blodgett Memorial Airport and Ivato International Airport. You'll see that it will travel the same route of the red line on this map!
