A company owned by Microsoft’s cofounder just unveiled the biggest plane in the world

Like the An-225, the Stratolaunch plane is powered by six high-bypass-ratio turbofan engines.
Stratolaunch, owned by Microsoft cofounder Paul Allen, intends to use the aircraft to move forward with its vision to “provide convenient, reliable, and routine access to low-Earth orbit.”

For decades, Ukraine’s Antonov An-225 has reigned supreme as the largest plane in the world.

That is, until now.

On Wednesday, Stratolaunch rolled its low-orbit-launch aircraft out of the company’s hangar in the California desert for the first time.

With wings spanning 385 feet, it is the world’s largest airplane by wingspan — besting the An-225’s 290 feet. The aircraft is also 238 feet long and 50 feet tall.
