“Boeing Co. once helped the U.S. beat the Soviet Union in the race to the moon. Now the company intends to go toe-to-toe with newcomers such as billionaire Elon Musk in the next era of space exploration and commerce. Boeing Chief Executive Officer Dennis Muilenburg sketched out a Jetsons-like future at a conference Tuesday, envisioning a commercial space-travel market with dozens of destinations orbiting the Earth and hypersonic aircraft shuttling travelers between continents in two hours or less.
