The first airplane flight was in 1903, and commercial air travel was common by the 1950s. The first person in space was 1961 and with SpaceX we might be on the verge of commercial space travel, or more likely automated supply missions to Mars. We do need a major advancement in propulsion technology to make roundtrips to Mars, so people aren't stranded there.
