About this route:
A direct, nonstop flight between Castle Airport (MER), Atwater, California, United States and Edwards Air Force Base (EDW), Edwards, California, United States would travel a Great Circle distance of 227 miles (or 366 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 Edwards Air Force Base, the route shown on this map most likely still appears to be a straight line.

Facts about Castle Airport (MER):
- The closest airport to Castle Airport (MER) is Merced Regional Airport (MCE), which is located only 7 miles (12 kilometers) SSE of MER.
- 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.
- 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 furthest airport from Castle Airport (MER) is Tôlanaro Airport (FTU), which is located 11,312 miles (18,204 kilometers) away in Tôlanaro, Madagascar.
- 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.
- 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.
- 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.
- It serves one school, Sierra Academy of Aeronautics, which specializes in training foreign pilots, from the People's Republic of China.
Facts about Edwards Air Force Base (EDW):
- There are a vast array of organizations at Edwards that do not fall under the 412th Test Wing.
- In the spring of 1942, however, the immense volume of flight test already being conducted at Wright Field, in Ohio, was one of the factors driving a search for a new site where a "Top Secret" airplane could undergo tests.
- At this time, another colorful character in Edwards' history, Pancho Barnes, built her renowned Rancho Oro Verde Fly-Inn Dude Ranch that would be the scene of many parties and celebrations to come.
- The success of these programs attracted a new type of research activity to the base in late 1946.
- The base is next to Rogers Dry Lake, an endorheic desert salt pan whose hard dry lake surface provides a natural extension to Edwards' runways.
- The P-59s were tested at Muroc from October 1942 through February 1944 without a single accident and, though the aircraft did not prove to be combat worthy, the successful conduct of its test program, combined with the success of the Lockheed XP-80 program which followed it in early 1944, sealed the future destiny of the remote high desert installation.
- The closest airport to Edwards Air Force Base (EDW) is Mojave Air and Space Port (MHV), which is located only 19 miles (30 kilometers) NW of EDW.
- The furthest airport from Edwards Air Force Base (EDW) is Pierrefonds Airport (ZSE), which is located 11,414 miles (18,369 kilometers) away in Saint-Pierre, Réunion.
