It is a sad day. Not for Texans or Americans or scientists, BUT FOR THE WORLD. Everything related to space travel and research is important not just for one nation, but for the future of humanity. It is a tragedy that some have died so that others can learn. It is also a tragedy that political leaders would use such a sad accident as a patriotic rally, to wave more american flags. Fuck the american flag… good people.. human people… working for humankind… died today. Let us remember them and work harder at what they believed in, not at ignorant nationalism.
