I think after they have failed in space now is the time to waste more money to dig the ground, well I suppose those billions of dollars should be spent somehow you agree?
Also many countries still haven't yet completely managed to build their metro, but maybe he can enjoy driving in tunnels with 200KM/s.
What kind of failure they lost in space? Recently I heard that they made a good start. They put into orbit a reconnaissance satellite and the main stage of the rocket returned. It seems to me that you have incorrect information.
