L'AEROFOTOTECA NAZIONALE RACCONTA....Come nasce un'industria di guerra strategica? Il caso della SLOI di Trento

Some time ago I came across a "singular story" and I tried to analyze it using indicators, I hope sufficiently neutral, to compare the congruity of the events compared to the story told by the SLOI of Trento, in which from 1939 to July 1978 Lead-Tetra–Etyle was produced -Etile (TEL, Tetra...

TEL, once mixed with a halogenated derivative of ethylene ('scavenger' required to ensure the mechanical integrity of the engine), formed the compound known as Ethyl-Fluid.
