Avraham Roos asked: > Does anyone know where, when and why the word "pilot" because "test" or > "trial". The Barnhart Dictionary of Etymolgy says: "The adjectival meaning of serving as a guide, prototype or experimental version of some project or undertakikng (as in a pilot study, a pilot program, a pilot film) is first recorded in 1928." The std derivation of "pilot" is from Greek pedon = steering oar. I think the reversal of "dolphin" has influenced its meaning. The pilot whale is a true dolphin. Order:Cetacea Suborder:Odontoceti Family:Delphinidae Genus:Globicephala Notice the connection with "Delphi", the oracle of Apollo and hence the association with determining the future. The dolphin / porpoise swims in front of sailing ships as if it were leading them.
