The biggest airplane ever built, Stratolaunch’s Roc carrier aircraft, just aced its fourth test flight.

Roc, which will eventually haul hypersonic vehicles into the air, successfully finished its latest flight on Thursday (Feb. 24), a jaunt that came on the heels of another test flight in January.

Roc lifted off from the Mojave Air and Space Port in California at 3:23 p.m. EST (1823 GMT) and stayed aloft for 1 hour and 43 minutes, reaching a maximum altitude of 15,000 feet (4,572 meters), Stratolaunch representatives said. The huge aircraft has a wingspan of 385 feet (117 m), more than double the wingspan of a typical commercial airplane.
