Yes I do Anthony, it was death by 1000 cuts because they manufactured their
own HTP in house which put an unnecessary strain on their resources
which otherwise could have been eliminated with an OTS propellant. At least
their hydrocarbon fuel was OTS.

Hi Ken,
Do you believe the choice of the oxidizer was a contributing factor? If
so, how?
Thanks.

For most uses, though, torch
igniters seem quite satisfactory.
I second that with >1000 successful torch ignitions under my belt.
Years ago I turned down a job with Beal Aerospace because he wouldn't
budge from HTP as his main/only oxidizer.
When I suggested he think about alternative oxidizers like LOx, he nearly
got angry. With such a closed mind attitude I felt the company's days were
numbered.
The rest is history.

oxidizer uses RGHP and the fuel is NOT petroleum-based (e.g. RP1,
Kerosene, etc.).
I take it RGHP is "rocket grade hydrogen peroxide"?
To me, the main market for hypergolics seems like it's orbital
maneuvering. Brief pulses of thrust which have to be precise are a
scenario where self-ignition can be a big plus, and since less fuel is
involved, fuel cost is less of an issue. For most uses, though, torch
igniters seem quite satisfactory.
