Its the end of AD 2009 and you ask where is your Flying Car?

Now that the Third Millennium is underway, many of you are suffering from retrofuturian nostalgia, which consists of wondering what ever became of the flying car and the jetpack, foodpills and robot maidservants, not to mention the moonbase, all those Hugo Gernsbeck stories promised you?

Well, I say, to frell with that! You dare to whine about your missing jetpack? Where is my land ironclad? You might have been promised a flying car! I want to know where is my gnormously awesomtastic armored hypersupertank bolo mark x??

Keep your flying car! Where is my Land Battleship?

The caption reads: 
FUTURE WAR TANK
This land battleship can form the spearhead of attack in future wars.

It will be used to penetrate and smash strategic enemy positions and hold them until support arrives. Massively armored, they [sic] will brush aside ordinary tanks. Only direct hits by heavy guns will affect it. Its anti-aircraft guns will repel aerial attack. Flame throwers will demoralize infantry resistance. Trenches and fortifications will be crumbled. Its crew will defend captured positions for days if need be. Its great weight will pave a road for following infantry and field artillery. Its guns will cover their advance.

In the book DARKNESS AND LIGHT, writer of futurist fiction Olaf Stapledon describes the last war between Russia and China leading to the rise of the unified world empire: 

 

In the decisive campaign the Chinese used two new inventions against which the orthodox methods of Russia were powerless. One was the giant tank, the other the legged aeroplane. The new Chinese tank was so large that to call it a land-battleship was to disparage it. This new engine was indeed a moving fortified town, complete with its own workshops, and food stores for its thousand men for three weeks. It could crush and trample modern sky-scraper cities. On good ground it moved at a hundred miles an hour. It could travel over mountainous country by using its great clawed mechanical arms or legs. The legged aeroplane had the great advantage that it could land anywhere and take off anywhere. It was indeed a giant mechanical fly which could cling to precipitous places or suddenly leap from the ground by kicking with its prodigious thighs. Some hundreds of the new tanks, each attended by its own swarm of the new aeroplanes, advanced through central Asia. Russian bombers attacked in successive waves of a thousand planes, but their bombs could not harm these armour-plated monsters, whose artillery swept them from the sky. Unchecked, these greatest of all man’s engines streamed across the prairies and deserts of Outer Mongolia, flattened out the forest, crossed the mountain barriers, turned aside here and there to grind a town to rubble, took the Urals in their stride, and headed for Moscow. The Russian government fled. The city surrendered. But the enemy, obsessed with the worship of cruelty and ecstatic with slaughter, hurried on to catch the city before it could be evacuated. Arrived, the monsters steam-rollered the whole urban area into a flat waste of rubble. The sacred mummy of Lenin was pulverized in the general ruin. The invaders then amused themselves by overtaking and squashing the hosts of refugees as a man may crush a swarm of ants under his boot. Leningrad and other cities were similarly treated.
