Watch: The worlds largest airplane takes its first flight

Earlier today before sun rise over the Mojave Desert, the largest airplane ever to be created was flown for the very first time.

The aircraft constructed and designed by Stratolaunch has a record breaking 385-foot wingspan and has been 8 years in the making.

Stratolaunch hopes to use the twin-fuselage, six engine, catamaran-style aircraft to launch satellite-bearing rockets into space by 2022.

The company reported the airplane was able to hit speeds of 189 miles per hour and heights of 17,000-feet during its 150-minute flight test, and test pilot Evan Thomas told reporters it ran smoothly.

It is a goal for the company to soon see the large aircraft carry 250-tonne rocket ships loaded with satellites to a height of 35,000 feet, with further hopes to carry the aircraft and its satellite cargo into space.

The airplane's six Pratt & Whitney engines and 28-wheel landing gear were originally designed for Boeing 747s, but aerospace company Scaled Composites worked alongside Stratolaunch and repurposed three 747s to put it together.

Long-time space enthusiast and Microsoft co-founder Paul Allen funded the stratolaunch project but unfortunately passed away last October.

Its take-off weight is 1.3 million pounds.
