SpaceX and Blue Origin are targeting reusable rockets. The reusable rocket age should have started in the 1980s. However, cost-plus contracts and political bureaucracy split manufacturing of the shuttle into 50 states. The plan was for shuttle flights to happen once a week and to be $5 million instead of the $1+ billion that they did cost.
There has been a 40-year delay to the fully reusable rocket age. Elon and Jeff are aware of the history of commercial air travel as bigger and more efficient planes developed from the 1920s to today.
Elon with the BFR will be leaping the reusable rocket age to the equivalent of the 1950s or 1960s in commercial aviation. The BFR could bring the cost per launch down to $5 million.
The US government needs to get out of the corruption of the Space Launch System and Lunar Gateway where $5+ billion per year will be wasted. These funds should be used to boost the US and world economy with many trillions of dollars per year from new space industries.
