The program required a Pratt & Whitney advanced rocket engine using liquid hydrogen/oxygen propellants.[^5] Total mission duration was projected at 1 hour 15 minutes from launch to landing.[^6]\n\n## Legacy\n\nWhile never reaching production, RHEINBERRY advanced concepts for near-orbital reconnaissance platforms and influenced subsequent aerospace programs.[^7] The project demonstrated potential for rapid-response intelligence collection capabilities beyond existing satellite systems.[^8]\n\n[^1]: [CIA CREST, \"Advanced Aircraft Program\" (CIA-RDP90B00170R000200310001-8)](https://www.cia.gov/readingroom/document/cia-rdp90b00170r000200310001-8)\n\n[^2]: [CIA CREST, \"Advanced Aircraft Program\" (Project ISINGLASS vulnerability note)](https://www.cia.gov/readingroom/document/cia-rdp90b00170r000200310001-8)\n\n[^3]: [CIA CREST, \"Advanced Aircraft Program\" (McDonnell concept and prior programs)](https://www.cia.gov/readingroom/document/cia-rdp90b00170r000200310001-8)\n\n[^4]: [CIA CREST, \"Advanced Aircraft Program\" (high-temperature metals and heat protection)](https://www.cia.gov/readingroom/document/cia-rdp90b00170r000200310001-8)\n\n[^5]: [CIA CREST, \"Advanced Aircraft Program\" (Pratt & Whitney hydrogen/oxygen rocket engine)](https://www.cia.gov/readingroom/document/cia-rdp90b00170r000200310001-8)\n\n[^6]: [Dwayne A.
