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

About this route:

A direct, nonstop flight between Eareckson Air Station (SYA), Shemya, Alaska, United States and Shearwater Heliport (YAW), Shearwater, Nova Scotia, Canada 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 Eareckson Air Station and Shearwater Heliport, 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 Eareckson Air Station and Shearwater Heliport. You'll see that it will travel the same route of the red line on this map!

Facts about Eareckson Air Station (SYA):

• The base host squadron was re-designated the 5073rd Air Base Squadron on October 1962, and upgraded to a group on 15 October 1974 in recognition of the number and complexities of the tenant units it supported.
• 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.
• 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.
• Eareckson Air Station (SYA) currently has only 1 runway.
• Additional aircraft and personnel reductions occurred in 1945 and almost all air bases other than Alexi Point, Shemya and Davis in the Aleutians were reduced to caretaker status.
• 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.

• In addition to being known as "Shearwater Heliport", other names for YAW include "Halifax/Shearwater Heliport", "12 Wing Shearwater" and "CFB Shearwater".
• 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.
• By the 1980s this air show came to be named the "Shearwater International Air Show" and was a popular event for military aviation enthusiasts in Eastern Canada and the Northeastern United States as the location of CFB Shearwater, coupled with the popularity of the Halifax area among military aircrew, resulted in heavy international participation from the RCAF, as well as the USAF, United States Navy, United States Marine Corps, Royal Air Force and numerous other NATO air forces in Europe.
• The closest airport to Shearwater Heliport (YAW) is Halifax Stanfield International Airport (YHZ), which is located only 17 miles (27 kilometers) N of YAW.
• 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.
• These changes allowed for heliport operations including instrument approaches and were accompanied with the construction of other non-airfield facilities in support of the Maritime Helicopter Project.
