Nonstop flight route between Changi, Singapore and Havre, Montana, United States:

About this route:

A direct, nonstop flight between Singapore Changi Airport (SIN), Changi, Singapore and Havre City-County Airport (HVR), Havre, Montana, United States would travel a Great Circle distance of 8,442 miles (or 13,585 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 Singapore Changi Airport and Havre City-County 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 Singapore Changi Airport and Havre City-County Airport. You'll see that it will travel the same route of the red line on this map!

Facts about Singapore Changi Airport (SIN):

• Resurfacing works costing S$50m on its dual runways and older taxiways were announced in January 2007 along with improvements to the security systems of Changi Airport such as access controls and surveillance systems to make the airport safer for travellers.
• The first phase costing about S$1.3 billion opened on 1 July 1981 with the first flight, Singapore Airlines Flight 101, touching down at 0700 hours UTC with 140 passengers from Kuala Lumpur.
• Changi Airport has two parallel runways, 02L/20R and 02C/20C, each 4,000 by 60 m.
• The closest airport to Singapore Changi Airport (SIN) is Paya Lebar Air Base (PLAB) (QPG), which is located only 6 miles (9 kilometers) W of SIN.
• The furthest airport from Singapore Changi Airport (SIN) is Francisco de Orellana Airport (OCC), which is nearly antipodal to Singapore Changi Airport (meaning Singapore Changi Airport is almost on the exact opposite side of the Earth from Francisco de Orellana Airport), and is located 12,345 miles (19,868 kilometers) away in Coca, Ecuador.
• Concerned that the existing airport was located in an area with potential for urban growth, which would physically hem it in on all sides, the government subsequently decided in 1975 to build a new airport at the eastern tip of the main island at Changi, at the existing site of Changi Air Base, where the new airport would be easily expandable through land reclamation.
• Singapore Changi Airport (SIN) has 3 runways.
• Because of Singapore Changi Airport's relatively low elevation of 22 feet, planes can take off or land at Singapore Changi 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.
