Nonstop flight route between Grand Forks, North Dakota, United States and Altamira, Pará, Brazil:

About this route:

A direct, nonstop flight between Grand Forks Air Force Base (RDR), Grand Forks, North Dakota, United States and Altamira Airport (ATM), Altamira, Pará, Brazil would travel a Great Circle distance of 4,461 miles (or 7,180 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 Grand Forks Air Force Base and Altamira 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 Grand Forks Air Force Base and Altamira Airport. You'll see that it will travel the same route of the red line on this map!

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.
• 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.
• With the restructuring of the Air Force and the disestablishment of SAC in 1992, the wing transferred to Air Combat Command, then came under Air Force Space Command in 1993.
