Salute!
Remember, jettisoning the plane with no motor providing power, as in gliding, has the EPU running on hydrazine. One gee pitch command and zero roll rate command.
If in a fairly level attitude with low bank, time after time the thing gradually slows to the limiter and descends on a fairly shallow angle. We had one at Hill that actually "crash landed" and the pilot climbed over a rise to see the thing with a busted main gear, EPU firing and beacon on the tail still flashing!!!
Look at pics of that Thunderbird a coupla years back. He had about 600 or so pounds remaining, but motor quit cause he pulled throttle to cutoff versus idle when the latch mechanism failed. No fire.
Gums sends...
EDIT: A dash cam of the crash shows a steep bank, so there could be more to the ejection condition than running outta gas. FLCS? But most outright FLCS failures have been extreme nose down, not roll .OTOH, one of our guys had the uncommanded EPU overvoltage problem that fried the computers and he flew for several minutes on aircraft battery, etc. Thing finally started a series of barrel rolls and he had to get out.
