About this route:

A direct, nonstop flight between Grand Forks Air Force Base (RDR), Grand Forks, North Dakota, United States and Hyder Seaplane Base (WHD), Hyder, Alaska, United States would travel a Great Circle distance of 1,477 miles (or 2,376 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 Grand Forks Air Force Base and Hyder Seaplane Base, the route shown on this map most likely still appears to be a straight line.

Facts about Grand Forks Air Force Base (RDR):

  • In 1973, the 319th Bomb Wing acquired the AGM-69 Short Range Attack Missile, replacing the older AGM-28 Hound Dog air-to-ground missile aboard its B-52H aircraft.
  • The DC-11 SAGE blockhouse was later the headquarters of the SAC 321st Strategic Missile Wing.
  • Due to the continuance of the Cold War between the United States and the Soviet Union, GFAFB was originally an Air Defense Command fighter-interceptor air base.
  • On 26 May 1972, President Nixon and Soviet general secretary Leonid Brezhnev signed the ABM Treaty, which limited each nation to one site to protect strategic forces and one site to protect the "National Command Authority." With work about 85 percent complete at Grand Forks, the United States chose to finish construction at the North Dakota site.
  • In May 2005, DoD's 2005 BRAC recommended GFAFB for realignment.
  • In addition to being known as "Grand Forks Air Force Base", another name for RDR is "Grand Forks AFB".
  • The furthest airport from Grand Forks Air Force Base (RDR) is Margaret River Airport (MGV), which is located 10,504 miles (16,904 kilometers) away in Margaret River, Western Australia, Australia.

  • The furthest airport from Hyder Seaplane Base (WHD) is Port Alfred Airport (AFD), which is located 10,540 miles (16,962 kilometers) away in Port Alfred, South Africa.
  • Because of Hyder Seaplane Base's relatively low elevation of 0 feet, planes can take off or land at Hyder Seaplane Base 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.
