I believe that these extra-terrestrial vehicles and their crews are visiting this planet from other planets. Most astronauts were reluctant to discuss UFOs. ↗
Before we had airplanes and astronauts, we really thought that there was an actual place beyond the clouds, somewhere over the rainbow. There was an actual place, and we could go above the clouds and find it.there. ↗
I'm Chinese-American, of course, and so it's very interesting to see China actually launch their own astronauts, becoming the third nation, following the United States and Russia, to do so. ↗
So most astronauts getting ready to lift off are excited and very anxious and worried about that explosion - because if something goes wrong in the first seconds of launch, there's not very much you can do. ↗
