Review of the Air Force Academy The Scientific Informative Review, Vol IX, No 1(18)/2011 Celebrating 30 years from the first flight in the outer space of a Romanian: Dumitru Prunariu First of all, a spaceflight provides a person with a different perspective of the surrounding world, starting from the very physical perception of the Earth, seen from the outer space. Moreover, all of these perspectives enlarge one’s horizon with regard to perceiving problems globally. This phenomenon does not take place immediately after experiencing a spaceflight, but in time, once one starts confronting oneself with a series of new activities, especially in international context. After a thorough analysis of such activities, the resulting conclusions are in most cases ignored by those people who do not possess a sense for perceiving things at a cosmic scale... I am absolutely convinced that Life is not only a terrestrial characteristic; it would be absurd for one to display such thinking.
