This writing has been prepared on the occasion of the 75th birthday ofE.C.George Sudarshan, who (besides the originator of the V-A theory forweak-forces, of quantum optics --the quantum representation of coherentlight--, of dynamical maps for open quantum systems, of the Zeno effect, etc.)was a pioneer, already in the sisties, also of the theory of the so-called"tachyons".  This paper wishes to be a homage to E.C.G.Sudarshan, in connection with thelast-mentioned pioneering work of his. After a brief theoretical introduction(based on the standard postulates of Special Relativity, and thereforeextending it --or rather non-restricting it-- without any violations: forexample, without any violations of the so-called Einstein causality), the mainaim of this article is an updated presentation of the status-of-the-art of the"superluminal" experiments. In particular, we devote such a review to thephenomena met in tunneling through quantum (and classical) barriers [e.g.,referring to the Genelalized Hartman Effect]; and in connection with the"Localized (nondiffracting) Solutions" of the wave equantions [e.g., of Maxwellequations]: especially of the "X-shaped" ones.  The interested reader is provided with an extended Bibliography.
