About this route:
A direct, nonstop flight between Asosa Airport (ASO), Asosa, Ethiopia and Castle Airport (MER), Atwater, California, United States would travel a Great Circle distance of 8,788 miles (or 14,143 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 Asosa 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 Asosa Airport and Castle Airport. You'll see that it will travel the same route of the red line on this map!

Facts about Asosa Airport (ASO):
- Asosa Airport (ASO) currently has only 1 runway.
- The furthest airport from Asosa Airport (ASO) is Manihi Airport (XMH), which is nearly antipodal to Asosa Airport (meaning Asosa Airport is almost on the exact opposite side of the Earth from Manihi Airport), and is located 12,128 miles (19,518 kilometers) away in Manihi, French Polynesia.
- The closest airport to Asosa Airport (ASO) is Beica Airport (BEI), which is located 44 miles (70 kilometers) S of ASO.
- Because of Asosa Airport's high elevation of 5,121 feet, planes must typically fly at a faster airspeed in order to takeoff or land at ASO. Combined with a high temperature, this could make ASO a "Hot & High" airport, where the air density is lower than it would otherwise be at sea level.
Facts about Castle Airport (MER):
- 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 is a public use airport located seven nautical miles northwest of the central business district of Merced, a city in Merced County, California, United States.
- Castle Airport (MER) currently has only 1 runway.
- It was estimated that the cost to relocate the 129 RQW to Castle, to include associated military construction costs, could be recouped in seven years.

- 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.
