Thanks for the context ... it seems to be a very rare book, the British Library seems not to know of it! No worries, once you’ve got images up they really eat up the bandwith.

It has the full Peace Treaty in it and the articles of the League of Nations. It has various commentaries of the future by notable people of the time King George, Lloyd George, President Wilson, Archbishop of Cantebury .... and thewn it just dives into a load of maps showing economic and commercial geography as you can see from my site. No where does it suggest that these maps are visionary, the map you've commented simply has a title of "The World: Principal Air Routes; Types of Aircraft". As I said, it smacks of propaganda. The British ruling classes never really levelled with the masses, they were never considered "up to the job" of understanding the complex issues in the World. They soon paid the price as the massive change in Britain post WWI which saw a lot of change. BTW, I'm going to be cheeky now because the website hosting costs me a good deal each year, not in storage but bandwidth in excess of 200Gb per month, so any donations by your readers would be most welcome, just click the "Donate" button on my site.

But I take it the atlas doesn't really explain what the map is supposed to show? Btw, thanks for putting the map online!

I'm afraid I can't confirm the date of the map exactly because, as was very common in those days, they never dated the atlas. However, on reading through it there is mention of statistics "...by the end of 1919 ..." but no later, so I'm guessing it was written if not published in 1920. I would never have questioned the map, as I'm not into air travel, I'm amazed that it is so inaccurate, I suspect there is some post war propoganda going on. Jonathan Hi,

I'll defer to him as he is clearly much more of a map geek than I am! On Chris's answer to CK's question, yeah what he said. I think the key point is that Glenn's orbit was inclined to the equator (as are most orbits), which, when projected onto the map of the Earth, explains the apparent "waviness" of the orbital ground trace. Also, as the Earth was rotating beneath Glenn as he orbited, the traces don't match up but shift along with each orbit. HTH!

The orbiting spacecraft always travels in a plane which passes through the center of the earth, and that's also the center of the circle it follows (for a general elliptical orbit it would be one of the foci). For simplicity let's also assume that the spacecraft's orbital period is much shorter than a day, so that the rotation of the earth beneath the spacecraft may be ignored. So the plane of the orbit divides the earth into two arbitrary hemispheres; the orbits therefore trace out <a href="http://en.wikipedia.org/wiki/Great_circle" rel="nofollow">great circles</a> on the earth's surface. The Glenn orbit maps show a roughly circular orbit inclined by about 30 degrees passing over the United States (not surprisingly given where he started). Life is harder if you want to plot arbitary other trajectories (for instance highly elliptical orbits, orbits with periods ~24 hours, parabolic trajectories as of missiles, etc.) and the above discussion doesn't apply in full. However, the plane of the orbit must still pass through the center of the earth and therefore still divides the (notionally spherical) earth into two equal hemispheres.

(A 1920s dirigible could make, what, 100km/h? So I guess each contour is roughly another day's flight by airship, ignoring winds; though to do so would be a very bad decision for the captain of an airship!)
