World's largest airplane will stretch over a football field and be 60% longer than the current biggest aircraft

This is the Radia WindRunner, a proposed cargo aircraft that, once completed, will become the world’s largest airplane.

It will be about twice the size of a Boeing 747 or an Antonov An-124

A full-scale mockup was unveiled at Paris Air Show, and the idea is to hit the skies by 2030.

Unfortunately, there’s a pretty significant issue that needs to be sorted out first.

The idea behind the world’s largest airplane

Radia WindRunner, developed by a Colorado-based startup, is an ultra-large cargo plane designed to transport oversized loads.

Specifically, the idea is to transport wind turbines, which has never been done before by plane.

At 108 meters (356 feet), WindRunner is nearly twice as long as an Antonov An-124 and a Boeing 747-400, which both measure around 70 meters (231 feet, give or take).

According to Radia, the plane would transport about 50-60 percent more payload than the aforementioned aircraft.

The fact that Radia unveiled a full-scale WindRunner mockup is promising because it moves the project one step closer to reality and away from being vaporware.

The goal is to obtain certification of airworthiness by 2030.

The only problem is that, so far, Radia has received around $150 million in funding, and that’s nowhere near enough.

The largest cargo planes in the world

After the destruction of the Antonov An-225 Mriya (84 meters), the Lockheed C-5 Galaxy (75 meters) inherited its ‘title’, and it is now the largest operational cargo aircraft in the world.

And we’re not talking about transporting potatoes or windbreakers, by the way.

The C-5 is the aircraft that the US security apparatus uses to transport ‘The Beast’, the presidential limo.

Sometimes, cargo planes are repurposed and used as private jets.

Drake’s jet, for instance, is an ex-Cargojet Boeing 767.

He got it for free as part of an endorsement deal with the company, but he then spent a fortune restoring it and turning it into a private jet.

Drake first unveiled the remodeled plane in 2024, but then overhauled it again completely in 2025.

While it might not be the biggest plane in the skies, it’s certainly one of the most lavish.

It looks halfway between a mansion and a nightclub now.
