Fell by the wayside, I don't know if it will be released or not.
Ah !! Cool

Does this refresh your memory ? There are 4 rotary switches in front of the thrust lever, lower left in pic 2.
Hmmmmmmmm, I'm picturing this on a Titan-II Launch stack lifting off from LC-41 in the early morning hours for a specops mission .........
Well, the current version of it has a Delta-Glider like specific impulse, no need for a launch vehicle... downgrading the engine specs to chemical specific impulses would result in the VTOL capability being practically useless.
Isn't that like rotary phones on the Enterprise? Meaning, if you have the tech for magic powered engines, why would the rest of it reflect late 60's era tech and design?
I think the idea of a winged launcher or a launch stack would finish it off nicely, give it a sense of proper "wholeness".
