American aerospace company Stratolaunch has successfully completed the second test flight of the world’s largest airplane above the Mojave desert in the US. The aircraft, with a 385-foot wingspan that’s longer than an American football field, flew for three hours at a maximum altitude of 14,000 ft. The aircraft is designed to transport hypersonic vehicles and facilitate easy access to space. The plane named Roc – with a wingspan of 117 metres and powered by 6 Boeing 747 engines – is being groomed to carry and launch supersonic vehicles high up in the sky.
