Original reading, mid- to late-1990s. Original review when I got LibraryThing in 2006ish (misspelling of weird and all):

A fun weave of half-baked theories and quarter-baked research. Was the US cooking up some wierd stuff? Sure. Did it include invisibility? Probably not. Did Moore and Berlitz have to engage in sloppy scholarship? No.

Second reading in 2023. New review:

To me it appears Moore did the lion's share of research and writing, and Berlitz was tacked on for publicity and sales. Moore appears to have been duped by some folks (on a newspaper clipping that appears to not exist), he is too credulous on Carl Allen, and he bounces around too much to make a proper case. The story of Jessup is the most interesting: his book on U.F.O.s, the annotations (by Allen only?), and the Varo Edition. But Moore is too credulous here too. Better research can now be found on the internet. To rehash my original review: did the U.S. try to make a ship invisible? Most likely not. Was it degaussing blown up by urban legend? Probably. A good book? Not really, but foundational for dozens of others in its ilk of government, conspiracy, ufology, etc. ( )

Really unconvincing attempt to make the reader believe that both a naval ship and naval personnel became invisible. The best part is the reproduction of the US Navy form letter. Nevertheless it is an entertaining even if you are just spotting the howlers. ( )
