(The video opens with a dramatic, sweeping 3D animation of the massive, grey Ekranoplan flying low over a choppy, dark sea. The sound is a deep, guttural roar of jet engines mixed with an ominous, low-frequency score.)
Narrator: In the middle of the Cold War, a CIA satellite took a picture of something impossible on the Caspian Sea. It was as big as a 747, but it had short, stubby wings and it was flying just meters above the water at over 500 kilometers an hour. Analysts were baffled. They called it the 'Caspian Sea Monster.'
(Cut to grainy, black and white satellite photos of the original KM Ekranoplan. Red circles and question marks are scrawled over them.)
They thought it was a prototype, a one-off experiment. They were wrong. This was just the beginning of a Soviet plan to build a fleet of war machines that could wipe out an entire US Navy carrier group in a single, devastating attack.

Building a machine that defies the conventional laws of flight requires a different way of thinking. It requires looking at a problem from a completely new angle. And if you're interested in learning from people who do just that, then you need to check out Nebula.
Nebula is a streaming platform built by and for independent creators. It's the only place you can watch exclusive videos from Mustard, like our deep dive into the legendary F-117 Nighthawk, or our look at the largest aircraft never built, the Lockheed CL-1201. And because Nebula is owned by the creators themselves, it's a place where we have the freedom to explore ambitious and fascinating projects that might not work anywhere else.
Like the brand-new Nebula Original from RealLifeLore, War Room, a monthly series that does an incredible deep dive into ongoing global conflicts, giving you the kind of context you won’t find in the daily headlines. Nebula also just got its biggest update ever, with new categories for Science and History that make it easier than ever to discover content you'll love.
Nebula is completely ad-free, and your subscription directly supports our channel and helps fund new, incredible content across the platform. By signing up using the link in the description, you’ll get a 40% discount on an annual membership. That’s unlimited access to thousands of exclusive videos and podcasts for just $2.50 a month.

To understand what the CIA was looking at, you have to understand a bizarre principle of aerodynamics that most aircraft try to avoid. It’s called the 'ground effect.'
(Simple 3D animation begins. A cross-section of a wing is shown flying high in the sky. Air flows smoothly over and under it.)
When a plane is flying at high altitude, the air pressure above and below the wing creates lift. But when a wing gets very close to a surface, like the ground or the water, something strange happens. The air underneath the wing gets trapped. It can’t escape. This creates a cushion of high-pressure air that pushes the wing upwards.
(The animation shows the wing moving closer to the water's surface. A pocket of dense, red-colored air forms beneath it, pushing it up.)
This cushion dramatically increases lift and reduces drag. In theory, a craft designed to use the ground effect could carry enormous weight with surprising fuel efficiency. And for the military, it had one other massive advantage. An aircraft flying just meters above the ocean would be almost completely invisible to enemy radar.
