These FORGOTTEN Aircraft Are ABSURDLY HUGE and RARE, You NEED to See This!

Hinzugefügt: 2026-05-18

[00:00:00]Have you ever stopped to imagine what aviation looked like before modern tech transformed flying forever? How did men working with slide rules and pure stubborn ambition build machines so enormous they barely seem to belong in our skies?

[00:00:14]The honest truth is that some old aircraft were so gigantic, so strange, and so rare that today they seem more like fantasy than fact. [music] You are about to take a ride through some of the biggest and rarest aircraft the world has ever seen. Forgotten giants that bent the rules, ignored the limits, and helped write entire chapters of aviation history. Stick with me all the way to the end because number one on this list is not just enormous. It is the kind of machine that rewrites what you thought an airplane could ever be. Tupolev ANT-20 Maxim Gorky In the mid-1930s, deep inside Stalin's Soviet Union, the Tupolev Design Bureau rolled out a machine that was less of an airplane and more of a flying monument to a regime.

[00:01:00]Built in 1934, the ANT-20 Maxim Gorky was created as a piece of airborne propaganda. An eight-engine giant meant to fly across the entire country and shout the message of the regime to anyone who happened to look up at the sky. With a wingspan of about 206 ft, [music] it was the largest land plane in the world at the time, and it carried something no other aircraft had ever hauled into the sky.

[00:01:23]>> [music] >> Inside its enormous fuselage, the Soviets installed a fully working printing press, a functional photographic laboratory, and even a small movie theater capable of showing propaganda films to people gathered below on the ground. Power came from eight massive piston engines mounted along the wings and above the fuselage designed to keep the aircraft airborne even when fully loaded with crew, equipment, and stacks of propaganda gear. Its cruising speed was modest since the focus was never on going fast.

[00:01:53]The focus was on presence, on scale, and on the political statement of having something this big circling overhead in the air. The pilots controlled the machine through fully manual systems. No servos, no computers, [music] only cables, muscle, and constant concentration. The landing gear was fixed and reinforced, and the cockpit sat high above the ground like the bridge of a ship. Visually, the Maxim Gorky was overwhelming. People who watched it pass overhead said the sky seemed to darken under its huge shadow.

[00:02:25]Its story ended in tragedy in 1935 when a small escort fighter attempting an unauthorized stunt collided with the giant in midair, killing 45 people in one of the most spectacular disasters in early aviation history. And if this Soviet flying palace already sounds like something pulled straight out of a science fiction novel, the next aircraft on our list takes us even deeper into Cold War strangeness.

[00:02:49]Bartini Beriev VVA-14.

[00:02:54]Now we step into one of the boldest and weirdest experiments the Soviet Union ever poured into a top secret hangar.

[00:03:01]The Bartini Beriev VVA-14 was developed during the 1970s, [music] designed by the brilliant and slightly eccentric Italian-Soviet engineer Robert Bartini with help from the Beriev Design Bureau right in the heart of the Cold War.

[00:03:16]The mission was as ambitious as it was unusual. Soviet planners wanted a machine that could hunt down American nuclear submarines anywhere in the world, taking off vertically straight out of the water, racing across the open ocean, and even skimming the surface like a flying boat when it needed to.

[00:03:32]>> [music] >> It measured roughly 85 ft long, had a wingspan of around 98 ft, and an estimated maximum takeoff weight close to 115,000 lb. It was not gigantic by some standards, but its silhouette looked like absolutely nothing else any human being had ever built. A wide central fuselage, thick stubby wings, twin tail booms, and a body that seemed to be part airplane, part hovercraft, and part secret military laboratory all rolled together into one strange package. Its primary thrust came from two Soloviev D-30 turbofan engines, each producing around 15,400 lb of force.

[00:04:13]>> [music] >> The original plans also called for an array of vertical lift engines that were supposed to let the aircraft jump straight up off the water like a giant cushion of air.

[00:04:22]But that crucial part of the dream never came together the way the Soviet engineers had hoped. Its top speed sat around 470 mph with an estimated range of more than 1,200 mi.

[00:04:34]There was no transmission, of course, just throttles, control levers, and a retractable landing gear built for runway tests and experimental flights.

[00:04:43]The cockpit looked small and almost lost inside that massive structure, >> [music] >> and the engines produced a sharp, modern sound that had nothing in common with the deep growl of older propeller machines from earlier years.

[00:04:56]In practice, the VVA-14 never reached front-line service. The program was quietly canceled by Moscow, and one of the last surviving examples now sits rusting at the Central Air Force Museum just outside Moscow, a haunting metal ghost of a project that pushed far too hard against the limits of physics and Cold War politics.

[00:05:17]Even today, photos of that decaying hulk still draw aviation fans from all over the world.

[00:05:22]>> [music] >> And if this anti-submarine UFO already feels strange enough to you, the next aircraft brings us back to the elegance of the great British flying boats.

[00:05:32]Saunders Roe SR.45 Princess. Few aircraft on this list capture the feeling of an entire era ending quite like the Saunders Roe Princess. Built in the United Kingdom in the early 1950s by Saunders Roe on the Isle of Wight, it arrived at the very moment the world was turning its back on giant flying boats and turning its eyes toward fast new jet airliners.

[00:05:54]The Princess was supposed to be the future of luxury transatlantic travel, a graceful ocean liner of the sky for wealthy travelers. It measured roughly 148 ft long >> [music] >> with a wingspan close to 219 ft, making it the largest all-metal flying boat ever constructed by anyone, anywhere.

[00:06:13]Power came from 10 Bristol Proteus turboprop engines mounted along the wings. With the inner engines coupled to drive contra-rotating propellers that gave the aircraft a unique twin-blade sound nobody else in aviation could match.

[00:06:27]Its top speed was around 380 mph with a range capable of crossing oceans without breaking a sweat.

[00:06:34]The cabin inside was designed with full pressurization, multiple decks, and the kind of comfort that promised passengers would arrive in New York or London feeling like [music] absolute royalty.

[00:06:45]There was no transmission like a car would have, only throttles, propeller controls, and the careful hand of a flight crew trained for difficult water takeoffs and landings.

[00:06:55]The landing gear, if you can even call it that, was the hull itself, designed to glide across the waves like a giant aluminum boat.

[00:07:03]Visually, the Princess looked impossibly graceful with its sweeping lines, twin engine pods, and a tall vertical tail that seemed to dominate the harbor whenever it taxied.

[00:07:15]The problem was timing.

[00:07:17]By the time it was finally ready to fly, jet airliners like the de Havilland Comet were already proving that flying boats were a thing of the past.

[00:07:25]Only one of the three Princesses ever built actually flew, and the dream of luxury ocean crossings by air quietly faded into history.

[00:07:34]And if this elegant British giant already feels like a forgotten masterpiece, the next aircraft on the list takes that bulging fuselage to almost cartoonish levels.

[00:07:44]Super Guppy. There are a few vintage aircraft that grab your attention as fast as the Super Guppy. It first appeared in the 1960s, developed in the United States by Aero Spacelines using heavily reworked structures borrowed from the Boeing 377 Stratocruiser. It stretched roughly 144 ft long, carried a wingspan of about 156 ft, and reached a maximum takeoff weight close to 170,000 lb.

[00:08:13]But, what really made people stop and stare was that swollen, balloon-shaped fuselage built specifically to swallow cargo that simply could not fit inside any normal airplane.

[00:08:24]The best-known version was powered by four Allison 501 turboprop engines, each putting out around 4,600 horsepower.

[00:08:32]Its top speed came in at about 285 mph with a useful range near 2,000 mi, depending on what was packed inside.

[00:08:41]There was no transmission, just throttles, propeller controls, and a flight crew that had to manage a beast shaped more like a whale than an airplane.

[00:08:49]>> [music] >> The landing gear was fully retractable, and the truly genius part of the design was the hinged nose, which swung open like a massive door to let oversized loads slide in.

[00:09:01]The Super Guppy had a profile that was almost impossible to take seriously at first glance. It looked bulky, tall, completely disproportionate, and somehow brilliant at the same time.

[00:09:13]The sound of those four big turboprops fit the body perfectly, slow, heavy, and absolutely necessary.

[00:09:21]It became a key tool in the American space program, carrying massive Apollo and later space shuttle components across the country for NASA when no other aircraft could do the job.

[00:09:32]Without machines like this one, the United States would have had a much harder time assembling the rockets that put men on the moon.

[00:09:38]And one Super Guppy is actually still flying today, hauling oversized parts for NASA.

[00:09:44]And if this bulging cargo monster already seems too cartoonish to be real, the next aircraft on the list went from dropping bombs to dropping water on wildfires. Martin JRM Mars.

[00:09:57]Coming in at number six, we have one of the most beloved flying boats ever built in America, the Martin JRM Mars.

[00:10:05]Designed during World War II by the Glenn L. Martin Company in the United States, it was originally created as a long-range patrol bomber to help the Navy track Japanese ships and submarines across the Pacific.

[00:10:16]It measured around 117 ft long with a wingspan stretching close to 200 ft and a maximum takeoff weight near 165,000 lb.

[00:10:26]By the standards of the 1940s, it was a true monster.

[00:10:30]One of the largest flying boats ever to leave an American hangar.

[00:10:34]Power came from four Wright R-3350 radial engines, each with 18 cylinders producing roughly 2,500 horsepower.

[00:10:43]Its top speed was close to 220 mph with a range that allowed it to stay aloft for entire days on patrol missions.

[00:10:51]The pilot did not have a transmission to worry about, only the four throttles, propeller controls, and the constant pressure of flying a machine that landed and took off on open water.

[00:11:01]The hull was reinforced like a ship and the inside could carry crew, cargo, troops, >> [music] >> or as it turned out later, thousands of gallons of water.

[00:11:10]Only seven Mars aircraft were ever built, which already makes them incredibly rare, but their second life is what made them legends.

[00:11:18]After the war, several were converted into water bombers and spent more than five decades dropping over 7,200 gallons of water at a time on raging wildfires across Western Canada.

[00:11:31]Generations of people watched them roar low over burning forests, scooping up water from lakes and unloading it on flames.

[00:11:38]Their final operational flight came in 2024, ending one of the longest aviation careers in history.

[00:11:45]And if this water bombing giant already sounds unforgettable, the next aircraft takes us back even further to a German flying machine that looked like it came straight out of a steampunk novel.

[00:11:55]Dornier Do X.

[00:11:58]The Dornier Do X first lifted off in 1929.

[00:12:02]Built in Germany by the Dornier company, and it remains one of the most jaw-dropping aircraft of the entire pre-war era.

[00:12:10]At a time when most airplanes were small, fragile machines with one engine and an open cockpit, the Germans rolled out a flying boat with 12 engines, three full decks, and a 60-ft dining salon inside.

[00:12:23]It measured around 131 ft long with a wingspan of about 157 ft and a maximum takeoff weight near 123,000 lb.

[00:12:33]The Do X carried its 12 engines stacked in tandem pairs mounted on struts above the wing with six pulling and six pushing.

[00:12:41]Each engine contributed to a combined output that pushed the aircraft to a top speed near 130 mph. Slow by modern numbers, but absolutely breathtaking for the late 1920s.

[00:12:53]There was no transmission, only the engine throttles, propeller adjustments, and an enormous reinforced hull that landed and took off on water.

[00:13:03]The interior was something nobody had ever seen in the sky before.

[00:13:06]Passengers walked through carpeted lounges, >> [music] >> ate full meals at proper tables, and looked out through big rectangular windows like they were on an ocean liner.

[00:13:16]Smoking rooms, a writing area, and even sleeping berths gave the Do X the feel of a luxury hotel that just happened to fly.

[00:13:24]Only three Do X aircraft were ever built, and their service career was short, hampered by underpowered engines and a global economy collapsing into the Great Depression.

[00:13:34]Still, when you look at the old photos today, it looks more like steampunk science fiction than reality.

[00:13:40]And if this 12-engine flying hotel already feels otherworldly, the next aircraft brings us into the darker side of aviation history.

[00:13:48]A Nazi German monster that was never meant to be seen again.

[00:13:52]Blohm & Voss BV 238.

[00:13:57]Coming in at number four is one of the most secretive and intimidating aircraft ever built in Nazi Germany, the Blohm & Voss BV 238.

[00:14:06]Developed during World War II by the Blohm & Voss company based in Hamburg, this enormous six-engine flying boat was designed to be the largest aircraft Germany had ever managed to put into the air.

[00:14:18]It measured roughly 142 ft long with a wingspan close to 197 ft and a maximum takeoff weight near 220,000 lb.

[00:14:29]At the moment it first lifted off the water in 1944, it was the heaviest aircraft anywhere in the world.

[00:14:36]Power came from six Daimler-Benz DB 603 inverted V12 engines, each producing around 1,750 horsepower, giving the aircraft a top speed near 264 mph and a planned long-range capability of more than 4,400 mi.

[00:14:55]The Nazis had big ambitions for the BV 238, imagining it as a long-range maritime patrol bomber, a heavy strategic transport, and even a possible weapon against Allied shipping convoys operating deep in the Atlantic Ocean far from any friendly coast.

[00:15:11]There was no transmission, just six throttles, propeller controls, and a flight crew managing one of the most mechanically complex aircraft of the entire war effort.

[00:15:20]>> [music] >> The hull was massive, reinforced like a warship, and equipped with several defensive gun positions scattered along the fuselage to fight off Allied fighters on the attack.

[00:15:31]Visually, the BV 238 looked like a flying battleship sitting low in the water, broad across the wings, with those signature German military lines that made it look both elegant and threatening at the same time.

[00:15:46]But only one prototype was ever completed, and its fate matched the growing desperation of the late war years for Germany.

[00:15:53]American P-51 Mustang fighters found it floating quietly on a calm German lake in 1944 and strafed it again and again with machine gun fire until it sank in the shallow water near the shore.

[00:16:07]No surviving examples exist anywhere in the world today, and the BV 238 has slipped into the shadows of aviation history as one of the rarest giants ever built.

[00:16:18]And if this drowned Nazi monster already seems unbelievable, the next aircraft is an American Cold War Colossus that took strategic bombing to a completely new scale.

[00:16:29]Convair B-36 Peacemaker.

[00:16:33]Now we arrive at number three, and one of the most ridiculous sounding aircraft ever to roll out of an American hangar, the Convair B-36 Peacemaker.

[00:16:44]Designed by Convair in the United States and entering service in 1949, the B-36 was the answer to one terrifying Cold War question.

[00:16:53]How do you drop a nuclear bomb anywhere in the world without needing to land at a forward base?

[00:16:59]The answer was to build the largest combat aircraft ever mass-produced.

[00:17:04]It measured around 162 ft long, with a wingspan of an unbelievable 230 ft, and a maximum takeoff weight close to 410,000 lb.

[00:17:15]The B-36 had a power setup that pilots still talk about today. Six 28-cylinder Pratt & Whitney R-4360 piston engines mounted as pusher props on the trailing edge of the wing, plus four General Electric J47 jet engines hanging in pods underneath.

[00:17:34]Air crews called it six turning and four burning. [music] And the sound of all 10 engines firing at the same time was something witnesses said you could feel in your chest from a mile away.

[00:17:44]Its top speed reached around 435 mph at altitude with a range of nearly 10,000 mi, allowing it to fly intercontinental nuclear missions without ever refueling.

[00:17:57]There was no transmission, only the throttles, propeller controls, and a cockpit full of dials, gauges, and switches that required [music] a flight crew of more than a dozen men.

[00:18:07]The B-36 had a presence on the ramp that made every other aircraft look small. It was the king of the Cold War sky for almost a decade before the jet age finally caught up to it.

[00:18:19]And if this colossal nuclear bomber already feels like the limit of what propellers could do, the next aircraft on the list rewrites the rules of flight altogether.

[00:18:29]A ekranoplan, the Caspian Sea Monster.

[00:18:32]Coming in at number two on this list is the Soviet Union's most jaw-dropping flying machine, the ekranoplan. In particular, the gigantic KM that took to the water in the 1960s.

[00:18:44]It was not really a normal aircraft, but a ground-effect vehicle designed to skim across the surface of the sea using the cushion of air trapped between its wings and the water.

[00:18:55]The KM measured roughly 302 ft long with a wingspan close to 123 ft and an estimated maximum weight north of 1.1 million pounds.

[00:19:07]When American spy satellites caught the first blurry images of this thing, [music] intelligence officers in the West did not know what they were looking at, and they nicknamed it the Caspian Sea Monster.

[00:19:18]Power came from 10 Dobrynin VD-7 turbojet engines, each producing around 28,000 lb of thrust, with most of them mounted near the nose to help the giant lift off the water.

[00:19:30]It could hit speeds near 310 mph, flying only a handful of feet above the waves with a profile that mixed seaplane, ship, and military transport into one impossible silhouette. [music] There was no transmission, just 10 throttles, and a crew controlling an aircraft that flew more like a hovercraft. Visually, the ekranoplan was beyond strange, with that giant fuselage, the cluster of engines near the front, and a tail that looked like it belonged on a warship.

[00:20:00]Soviet planners imagined it as a fast military transport >> [music] >> and possible attack platform.

[00:20:06]Today, the only surviving example sits beached on the shore of the Caspian Sea, a rusting monument to one of the boldest engineering gambles of the 20th century.

[00:20:16]And if this sea monster already feels like the peak of impossible aircraft, >> [music] >> the number one entry on our list is even more legendary.

[00:20:25]Hughes H-4 Hercules, the Spruce Goose.

[00:20:27][music] Sitting at number one is the most legendary and possibly the strangest giant ever to leave the ground, the Hughes H-4 Hercules, better known to the world as the Spruce [music] Goose.

[00:20:40]Designed and built in the United States during World War II by the eccentric billionaire Howard Hughes, this enormous flying boat was created to solve a wartime problem.

[00:20:50]German U-boats were sinking Allied cargo ships faster than they could be replaced, and somebody needed to build a transport that could fly troops and equipment across the Atlantic without touching the water.

[00:21:01]Hughes promised to deliver, and what he delivered was a machine almost beyond belief.

[00:21:06]It measured around 219 ft long with a wingspan of 320 ft, a record that stood from 1947 all the way until 2019.

[00:21:16]Power came from eight Pratt & Whitney R-4360 radial engines, each producing around 3,000 horsepower mounted along the leading edge of the gigantic wing.

[00:21:28]Because of wartime metal restrictions, the entire airframe was built almost entirely out of laminated wood, mostly birch, even though the press mocked it by calling it the Spruce Goose.

[00:21:39]There was no transmission, just eight throttles, propeller controls, and the iron will of Howard Hughes at the controls.

[00:21:47]On November 2nd, 1947, in front of skeptical congressional critics and a crowd of stunned witnesses, Hughes himself climbed into the cockpit, fired up all eight engines, and flew the H-4 Hercules for about 1 mile at low altitude over Long Beach Harbor.

[00:22:03]It only flew that one time and never lifted off again. Exactly one was ever built, and it still exists today, preserved indoors at a museum in Oregon.

[00:22:14]It is the ultimate definition of absurdly huge and absurdly rare.

[00:22:19]These rare old aircraft prove that size and rarity are never just a couple of numbers on a spec sheet. Every single one of them was born to solve a massive challenge. Whether that meant flying propaganda across an entire country, hunting submarines, ferrying luxury passengers across oceans, swallowing rocket parts for NASA, dumping water on raging wildfires, or pushing engineering so hard that the laws of physics had to bend a little.

[00:22:45]From the Soviet Maxim Gorky to the legendary Spruce Goose, we have seen 10 machines with completely different missions and completely different fates.

[00:22:54]But every one of them shares something in common. Presence, ambition, and the kind of jaw-dropping impact that that any aviation lover stop scrolling and just stare.

[00:23:04]These are not simply old airplanes. They are flying chapters of history built out of metal and wood, riveted together with noise, risk, raw genius, and engineering courage from an era when every new project had a real chance to change aviation forever.

[00:23:20]Now, I want to hear from you in the comments. Which one of these giants would you most want to walk up to and touch with your own hands? Which one had the most unforgettable look in your opinion?

[00:23:29]And which aircraft on this list had you already heard about before today?
