Hypersonic, high-altitude recon lifting body aircraft.

Started working on this over a year ago, but never ended up finishing it. Figured I'd go ahead and post it before SP2 rolls around as I have no plans to continue working on it & port it to SP2.

I haven't narrowed down specific flight specs, but it is possible to get the aircraft up to Mach 10, and I've gotten it as high as 150,000ft.

The engines have power stages that are activated by exceeding certain speeds at/above certain altitudes. The stage altitudes are 40000ft, 80000ft, and 100000ft, with stage speeds of 574kts, 1722kts, and 2876kts respectively.

AG1 activates engines.
AG8 toggles fly-by-wire. Meant to be used during stall/spin recovery.

The aircraft has no landing gear, and the fly-by-wire system is incomplete. The originally planned auto-tuning for different speeds and altitudes hasn't been implemented, and the aircraft can be very unstable at high altitudes and speeds of around Mach 9.5.

Feel free to finish it/make improvements to your liking, just be sure to provide proper credit.
