WebAssuming the 100 foot altitude causes the horizon to appear approximately 13 miles off, the 47 miles remaining means the Welsh coastline should still fall an impossible 1472 feet below the line of sight! 68) The … Web15 jan. 2009 · The Space Shuttle can reach a maximum height of about 500 km (actually a little more, but close enough). That’s 500,000 meters, or the second-to-last line of the table. For them, the horizon is almost 2600 km away! That means they can see almost the entire US by looking from one side of the Shuttle to the other. Cool.
