The largest plane in the world reached speeds of more than 120 miles per hous and raised its nose off the runway during a recent test.
According to the Daily Mail, the plane hit 126 miles per hour during a runway test at the Mojave Air & Space Port earlier this month.
When it's ready to fly, the plane — called the Stratolaunch — will produce 200,000 pounds of force. Microsoft co-founder Paul Allen, who recently died at age 65 after a battle with non-Hodgkin's lymphoma, supported the project.
The Stratolaunch has two fuselages and is powered by six engines. Its length of 238 feet is dwarfed by its massive wingspan of 385 feet, larger than the length of a football field.
Twenty-eight wheels support the aircraft when it's on the ground.
"I am excited to share that Stratolaunch has completed our first successful hot-fire test of the PGA Engine fuel preburner," said Jeff Thornburg, vice president of propulsion at Stratolaunch, according to the Daily Mail.
"This is the first step in providing the performance and highly-efficient design of the PGA engine. The hot-fire test is an incredible milestone for both the propulsion team and Stratolaunch."
The Stratolaunch was first rolled out in the summer of 2017, and it was reported at the time that it can handle a payload of more than 500,000 pounds.
