In 1970 made Chrysler Coperation Space Division
a Study for Upper stage for Various Rockets: Atlas, Titan IIID and Solid 260 inch/S-IVB
using very nasty stuff: Hydrogene and Fluorine and Lithium !

the liquid Lithium and Fluorine burns in Combustion chamber
that's cooled by hydrogen, who goes true the Combustion chamber taking more heat of Lithium and Florine reaction.

Also they study Hydrogene and Fluorine and Beryllium
this more a Hybrid rocket were the Beryllium is solid rocket fuel, burned by Fluorine or mixture of Oxygen and Fluorine
again cooled by hydrogen who goes true the Combustion chamber taking the heat of reaction.

Wow... that is a NASTY propellant mix!
Never argue with drunks, idiots, conspiracy theorists, or internet trolls. They'll simply drag you down to their level and kick your ass with experience.

alone the combination Fluorine and Beryllium

Beryllium so extrem toxic, they banned it use 10 years ago in the industry.
only one who use Beryllium is in nuclear application because of Neutron absorbing property.

On toxic fuel, I guess that this combination top them all: CIF5/MHF-5.
CIF5 is Chlorine pentafluoride,
MHF-5 is 55% Monomethylhydrazine, 26% Hydrazine and 19% Hydrazinium Nitrate

that stuff was consider as fuel for deep space probe main engine and RCS
it was even consider as RCS fuel for manned Mars space craft and it's Lander MEM in 1969 !

What were they planning for the materials used in the tanks and engines? That mix would rot virtually anything (including glass)!
