Aerozine/Nitrogen Tetroxide is a rather rare combination for rocket fuel. And be thankful for that. They’re both really nasty chemicals.
Titan used it, and some Russian rockets use(d) it.
The most common booster propellant combo is RP1/LOX.
Yes, it is nasty stuff. Whatever you call it.
One whiff in the lungs turns it to nictric acid.
I saw footage of the Shuttle landing at White Sands Missile Range (WSMR), They had a big fan on a truck that blew wind over Shuttle of a long time before they were allowed to exit the vehicle.
I lived in NM from 1972-1986, many of my Ham friends worked at the labs, military bases or NMSU.
Great bunch of engineers, electronic technicians and physicists.
