The word hypergolic doesn't mean that, but in spaceflight the term refers to a fairly specific group of compounds; Dinitrogen tetroxide and unsymmetrical dimethylhydrazine or monomethylhydrazine (UDMH / MMH).
- gcb0 8y agommh+nto is the only thing still being used in the west outside of missiles. even spacex use it for module maneuver. I think. not even sure why I know that. but china probably use the lesser hypergolic combinations for actuall lift off.
