Re: Space x starship
Don't underestimate Elon Musk. His company has designed and USED a fully reusable space craft that has gone into obit, docked with the international space station, (ISS) dropped off, and picked up astronauts and returned safely to earth.
Remember, 190 years ago, scientists claimed that if a train carried passengers at a greater speed than 12 miles/hour, all of the air would be sucked out and people would die.
Also, at the start of the 20th century, some fool in charge of the patent office said, "Everything thing can be invented, has already been invented". 3 years later. the Wright Brothers flew their plane for the 1st time. 66 years after THAT, man landed on the moon.
