The General Electric YJ93turbo jet was to be used in the XB-70 and the F-108. As i'm sure most of you know these aircraft were mach 3+ with JP-6 fuel. If I am remembering correctly they modified and had allot of test hours using HEF(high energy fuels) the JP-6 produced 18000 and the HEF’s made 26000 of thrust.
We also know that the Air Force has a HEF plant that they made there special boron fuels. So they have the ability to make the green burning fuel. The F-24 like vehicle was most likely made or maybe a modified f-23 is using these power plants with JP-6 for normal flight then the HEF for dashing over mach 3.
Thus making our green lady. What do all of you think about my hypothesis?
If you were going to make the Green lady how would you do it?

Boron compounds [boranes and carboranes] burn with a green flame. The low mass of the Boron atom and the high energy of combustion would give a rocket engine a high specific impulse if a suitable boron based fuel could be developed. Boron containing compounds are not suitable for use in jet engines because when they burn, they produce boron oxides which abrade the turbine blades in seconds...literally.
