Nonstop flight route between Shearwater, Nova Scotia, Canada and Shemya, Alaska, United States:

About this route:

A direct, nonstop flight between Shearwater Heliport (YAW), Shearwater, Nova Scotia, Canada and Eareckson Air Station (SYA), Shemya, Alaska, United States would travel a Great Circle distance of 4,895 miles (or 7,878 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 Shearwater Heliport and Eareckson Air Station, 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 Shearwater Heliport and Eareckson Air Station. You'll see that it will travel the same route of the red line on this map!

Facts about Shearwater Heliport (YAW):

• During the late 1990s and early 2000s the Shearwater airfield was scaled back significantly as the facility transitioned to a heliport with surplus lands identified and transferred to Canada Lands Company.
• Shearwater Heliport's primary mission remains as a heliport in support of the Royal Canadian Navy's Maritime Forces Atlantic warships with shipborne helicopters operated by 12 Wing, a unit of the Royal Canadian Air Force.
• Because of Shearwater Heliport's relatively low elevation of 144 feet, planes can take off or land at Shearwater Heliport 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.
• The closest airport to Shearwater Heliport (YAW) is Halifax Stanfield International Airport (YHZ), which is located only 17 miles (27 kilometers) N of YAW.
• In addition to being known as "Shearwater Heliport", other names for YAW include "Halifax/Shearwater Heliport", "12 Wing Shearwater" and "CFB Shearwater".
• The furthest airport from Shearwater Heliport (YAW) is Albany Airport (ALH), which is located 11,763 miles (18,931 kilometers) away in Albany, Western Australia, Australia.
• Defence cutbacks and unit and facility realignments from 1994 to 1996 saw CFB Shearwater stand down as a separate formation and the facility merged as an airfield attached to CFB Halifax.

• After the disastrous attack, the focus of Eleventh Air Force was shifted to a defensive posture in the event of retaliatory attacks from the Japanese.
• In August, after the Soviet Union declared war against the Japanese Empire, B-24s were dispatched on reconnaissance and intelligence-gathering missions to observe the Russian activity in the Kuriles.
• The closest airport to Eareckson Air Station (SYA) is Casco Cove Coast Guard Station (ATU), which is located 40 miles (65 kilometers) WNW of SYA.
• The station was also used by SAC Cobra Ball and other related projects which monitored missile-associated signals and tracks missiles during boost and re-entry phases to provide reconnaissance for treaty verification and theater ballistic missile proliferation.
• On 28 May 1943, a small detachment of Alaskan Scouts began reconnaissance of Shemya, a small, flat, uninhabited island 35 miles to the east of Attu.
• In addition to being known as "Eareckson Air Station", other names for SYA include "Shemya Air Force Base", "Shemya Army Airfield" and "  ".
• Because of Eareckson Air Station's relatively low elevation of 97 feet, planes can take off or land at Eareckson Air Station 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.
• The furthest airport from Eareckson Air Station (SYA) is Cape Town International Airport (CPT), which is located 10,668 miles (17,168 kilometers) away in Cape Town, South Africa.
