About this route:
A direct, nonstop flight between Bert Mooney Airport (BTM), Butte, Montana, United States and Shearwater Heliport (YAW), Shearwater, Nova Scotia, Canada would travel a Great Circle distance of 2,345 miles (or 3,774 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 Bert Mooney Airport and Shearwater Heliport, the route shown on this map most likely still appears to be a straight line.

- 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.
- 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.
