The hefty , double - bodied Stratolaunch plane — its wingspan of 385 feet ( 117 meter ) is the wide in the worldly concern — recently accomplish a new milestone that bring it one step closer to leave the ground .
In runway tests conduct on Sunday ( Feb. 25 ) at the Mojave Air and Space Port in Mojave , California , Stratolaunch achieved a taxi f number of 46 mph ( 74 klick / h ) , accordingto a tweetposted on Feb. 26 by Paul Allen , founder of Stratolaunch Systems Corp. and co - founding father of Microsoft .
In recent tests, the Stratolaunch — the world’s biggest plane by wingspan — reached new top speeds on the runway.
Stratolaunch , which weigh about 500,000 lb . ( 227,000 kg ) , can carry a payload of up to 550,000 lb . ( 250,000 kg ) . The massive aircraft will transport rocket launchers and planet bound for low Earth orbit , agree to the company’swebsite . [ Stratolaunch Test Photos : The World ’s Largest Plane in legal action ]
projectile launches from unsex location can be delayed or halted by inclement weather and may look hazards from airborne traffic . But deploying rocket and satellites from a moving aircraft such as Stratolaunch — which would take off from a runway and release its payloads from a cruising altitude of about 36,000 feet ( 11,000 meters ) — could reduce the peril of launching cancellations or delays from bad weather , making access to distance " more convenient , reliable and routine , " Stratolaunch representatives said on the companywebsite .
Stratolaunch resembles two conjoined airplanes connected by a central offstage . It apply six Boeing 747 engine and has two fuselages , or aircraft body ; the one on the rightfield is worry by the flight gang , and the one on the left family flight of stairs data systems . The center wing that unite the fuselages help to stabilize the aircraft and do as the attachment point for projectile shipment , according to the Stratolaunch website .
Allen shared video recording of Stratolaunch on Feb. 26 as it trundle down the runway " with all flying surfaces in seat , " he wrote on Twitter .
Stratolaunch firstleft its hangarin May 2017 , and in September , the aircraft ’s engines were testedfor the first prison term . The sheet firstrolled down the runwayin December 2017 , reaching a rails taxicab pep pill of 40 miles per hour ( 64 km / h ) as technician put the plane through its paces for direction and braking . The late trial build on its prior rails public presentation , and the plane is expect to be operational by the destruction of the decade , according to company voice .
