This is a duh idea started in the 50's with project "Pilot" or "Notsnik"
by Howard Wilcox
It's very obviously the cheapest way to orbit for a small payload.
What's happening now is useful payloads are getting small enough.
Make that rocket reusable and getting cubesats by the thousands in orbit
gets so cheap everyone will want their very own satellite.
Drone aircraft launchers and drone reusable rockets all day long.

I'm not sure if anyone saw this but I found it while researching
the Northrop TR108 peroxide motor.
What's rather interesting that Ventions, the Company running
this for DARPA and NASA, parallels a lot of what we have
been talking here on Arocket.
