What organization has developed a wide array of aircraft and space systems? I was reading a bit about the space travels and I took interest in the subject because the very notion of traveling to that vast space seems very attractive to me. I’m just wondering who is developing transportation facilities for those travels. Is it actually, safe to travel to the space?

I don’t know exactly who is into that business, but I reckon that all those travels will be under NASA, regardless of the fact that they are commercial. Still, you can’t leave those to some agency that is not highly specialized in that field primarily because of the safety. I think that I would never dare to travel to space no matter who would organize the trip because I know that the technology is not still so developed and it is still very expensive meaning that they haven’t found solutions for making it available for commercial use and I reckon that they’re still working on some safety issues which would reduce the possibility of crashing.
