Photograph of a close-up view of an electronic console, which controls large rocket engine test firings at Rocketdyne's Propulsion Field Laboratory, ca.1955. A man can be seen wearing a hearing and speaking device on his head; his arm extends to the right while his index finger is positioned on top of a button. The button is on a panel labeled "Engine Test" which displays several additional buttons which are under labels that read: "Vernier Engines", "Ignition" and "Main Engines". Further to the right, a telephone apparatus can be seen attached to what appears to be an operating box which shows several switches labeled "Lox[...] Pre-Va[...]", "Open", "B. Fuel Pre-Valve", "On", "#1 GN2 Recirc.", "#2 GN2 Recirc.", "On", and "On". In the back, a semi-circular machine is visible which exposes several circular measuring panels.; Photoprint reads: "Rocketdyne.
