After years of development in the desert north of Los Angeles, a gigantic, six-engined mega jet with the wingspan of an American football field flew Saturday morning for the first time.

“We finally did it,” said Stratolaunch Systems CEO Jean Floyd at a news conference from the hangar at Mojave Air & Space Port. “It was an emotional moment to watch this bird take flight.”Stratolaunch, the company founded in 2011 by the late Microsoft co-founder Paul Allen, conducted the first test flight of the world’s largest plane.

“I had imagined this moment for years, but I had never imagined it without Paul standing next to me,” Floyd said, adding that he whispered a private “thank-you” to Allen as the plane took flight.Allen died last October at age 65 from complications related to non-Hodgkin’s lymphoma.In simple terms, the Stratolaunch aircraft is a giant flying launch pad, designed to hurtle satellites into low Earth orbit.

It aims to offer the military, private companies and even NASA itself a more economical way to get into space. The company’s business model calls for getting satellites into space “as easy as booking an airline flight.”Test pilot Evan Thomas flew the jet to speeds of about 173 mph, climbing as high as 15,000 feet before returning smoothly and safely back, after a nearly two-and-a-half-hour flight.

“For the most part, the plane flew as predicted,” said Thomas, a former F-16 Air Force fighter pilot.”It was overall fantastic. I honestly could not have hoped for more on a first flight, especially of an airplane of this complexity and this uniqueness.”

The aircraft’s wingspan measures 385 feet — wider than any airplane on the planet. From tip to tail, it’s 238 feet long.

It weighs half a million pounds. It’s so big, it has two cockpits, one in each fuselage (but only one is used to fly the plane.)”It’s the world’s biggest airplane. It’s so huge, it seems like it shouldn’t be able to fly,” Jack Beyer, an aerospace and launch photographer for NASASpaceFlight.com, told CNN on Thursday. He’s excited to witness the beginnings of the space industry’s rising trend: using jets to launch satellites.Dozens of photographers, industry bloggers and aerospace enthusiasts gathered this week to glimpse the unique twin-fuselage plane.

“People are interested in the first flight of Stratolaunch because they want to see the future,” Beyer said. “It’s the same reason why people tune in each year to watch the Apple keynotes. People want to see what’s next.”
