About this route:
A direct, nonstop flight between Castle Airport (MER), Atwater, California, United States and Greenwood-Leflore Airport (GWO), Greenwood, Mississippi, United States would travel a Great Circle distance of 1,729 miles (or 2,783 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 relatively short distance between Castle Airport and Greenwood-Leflore Airport, the route shown on this map most likely still appears to be a straight line.

- 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.
- 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.
- 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.
- 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.
- Castle Airport (MER) currently has only 1 runway.
