“The first liquid hydrogen engine" Is there any reference or link where I might learn if the engine directly burning liquid hydrogen? or is it part of a system that stores hydrogen as a cryogenic liquid and heats it into a gas before giving it to the engine to burn?

(To exist as a liquid, H2 must be cooled below its critical point of 33 K. However, for it to be in a fully liquid state at atmospheric pressure, H2 needs to be cooled to 20.28 K (−252.87 °C).
