Not sure if any of you here read Air and Space magazine. The current issue has an article about and cover photo of a modified Starfighter that sports a 6 thousand pound thrust rocket motor fueled by peroxide and regular jet fuel. It was used for astronaut training in the air force. I forget the exact numbers but altitudes reached were in the 100000+ feet. These planes also had rocket motors for steering in the thin atmosphere ala X-15. Chuck Yeager was one of the champions of this project.
Unfortunately the article itself is a description of a zoom flight of a regular F-104 but it's still a good read. Not sure how much US residents were exposed to the F-104 but in Holland they flew over our town several times a week. *Lots* of noise. In any case, relevance for ERPS would be that this was a good example of a hybrid approach to reaching space, using the same fuel in both engines and only bringing oxidizer for the rocket motor of course. I imagine that with external fuel and peroxide tanks it could have gone even higher. Cool.
