ما هي أكثر المقاعد أمانا على الطائرة؟

This handout photograph obtained courtesy of Stratolaunch shows the Stratolaunch plane flying above the California desert, April 13, 2019, the first test flight of the US company's gigantic aircraft whose wingspan is almost half that of an Airbus A380. - The world's largest airplane -- a Stratolaunch behemoth with two fuselages and six Boeing 747 engines -- made its first test flight on Saturday, April 13, 2019 in California. The strange aircraft, built by the legendary aeronautical engineering company Scaled Composites in the Mojave Desert, has two fuselages and is powered by six Boeing 747 engines. It must theoretically be used to carry and drop at altitude a small rocket that will then light its engine, and will propel to space to place satellites in orbit. This is a more flexible method of accessing the space than vertical rocket takeoffs, as a large take-off runway would suffice.
