About this route:
A direct, nonstop flight between Hamadan Airport (HDM), Hamadan, Iran and Castle Airport (MER), Atwater, California, United States would travel a Great Circle distance of 7,396 miles (or 11,903 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 Hamadan Airport and Castle 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 Hamadan Airport and Castle Airport. You'll see that it will travel the same route of the red line on this map!

Facts about Hamadan Airport (HDM):
- Hamadan Airport (HDM) currently has only 1 runway.
- The closest airport to Hamadan Airport (HDM) is Shahid Ashrafi Esfahani Airport (KSH), which is located 87 miles (140 kilometers) WSW of HDM.
- The furthest airport from Hamadan Airport (HDM) is Totegegie Airport (GMR), which is located 11,597 miles (18,663 kilometers) away in Mangareva, Gambier Islands, French Polynesia.
- Because of Hamadan Airport's high elevation of 5,755 feet, planes must typically fly at a faster airspeed in order to takeoff or land at HDM. Combined with a high temperature, this could make HDM a "Hot & High" airport, where the air density is lower than it would otherwise be at sea level.
Facts about Castle Airport (MER):
- EPA investigations have been completed at multiple areas of contamination including landfills, discharge areas, chemical disposal areas, fire training areas, fuel spill areas, and polychlorinated biphenyl spill areas.
- Since the mid-1940s, aircraft maintenance, fuel management, and fire training activities on the base have generated wastes that consist primarily of waste fuels, oils, solvents, and cleaners.
- The EPA currently has this base listed on their database due to the bulk wastes such as solvents, oils, fuels, and sludges which were disposed in pits at landfills around the base until 1977.
- The furthest airport from Castle Airport (MER) is Tôlanaro Airport (FTU), which is located 11,312 miles (18,204 kilometers) away in Tôlanaro, Madagascar.
- Castle Airport covers an area of 1,360 acres which contains one runway with an 11,802 x 150 ft asphalt and concrete pavement.
- Castle Airport (MER) currently has only 1 runway.
- The closest airport to Castle Airport (MER) is Merced Regional Airport (MCE), which is located only 7 miles (12 kilometers) SSE of MER.
- Because of Castle Airport's relatively low elevation of 191 feet, planes can take off or land at Castle Airport at a lower air speed than at airports located at a higher elevation. This is because the air density is higher closer to sea level than it would otherwise be at higher elevations.
