Nonstop flight route between Hatfield, Hertfordshire, England, United Kingdom and Alamosa, Colorado, United States:

About this route:

A direct, nonstop flight between Hatfield Aerodrome (HTF), Hatfield, Hertfordshire, England, United Kingdom and San Luis Valley Regional Airport (ALS), Alamosa, Colorado, United States would travel a Great Circle distance of 4,823 miles (or 7,762 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 Hatfield Aerodrome and San Luis Valley Regional 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 Hatfield Aerodrome and San Luis Valley Regional Airport. You'll see that it will travel the same route of the red line on this map!

Facts about Hatfield Aerodrome (HTF):

• Hatfield Aerodrome (HTF) has 2 runways.
• The 146 first flew in 1981 and production of some components, final assembly and flight testing of the first two series of the aircraft was based at Hatfield during the early and mid 1980s.
• The furthest airport from Hatfield Aerodrome (HTF) is Chatham Islands (CHT), which is located 11,860 miles (19,086 kilometers) away in Waitangi, Chatham Islands, New Zealand.
• Because of Hatfield Aerodrome's relatively low elevation of 254 feet, planes can take off or land at Hatfield Aerodrome 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 ICAO code, EGTH, has subsequently been reallocated to Old Warden Aerodrome in Bedfordshire.
• In 1934 significant works were undertaken at the site and a large factory and imposing Art Deco administration buildings were constructed together with a flying school building which also housed flying control.
