Some say "seeing is believing"--but we can't believe everything we see, especially in satellite imagery taken from Google Earth.
The process of capturing, digitizing, and combining satellite images often produces digital artifacts (not to be confused with archeological artifacts!. With respect to the ELP sighting, Ric Gillespie wrote, "Under certain circumstances having to do with the sampling rate (which Jeff Glickman understands and I don't), the software that converts the data set to imagery tends to produce straight lines where none are present. A blob can appear as a series of straight lines and, of course, letters are composed mostly of straight lines. As several of you have pointed out, the human takes over from there."
TIGHAR receives about two Google Earth sightings of the Electra per week, on average. Some may be rejected out of hand because the aircraft would have to be the size of a Boeing 747 (the planform of the Electra was 55' x 38' 7"); others such as the "Electra on land" in the gallery below are rejected because TIGHAR teams have covered that part of the land or the lagoon and know for certain that what appears in the Google Earth images are not half-buried Electras.
