This is J-N eight-two-four-six (pg. 100) -- I'm no expert, but this strikes me as incorrect. I thougt it went: Aircraft manufacturer, aircraft number (often dropping the "November" for N). I don't see a "J-N" float plane manufacturer listed anywhere. Am I right, or am I wrong?
double-clutching (pg 169) -- Huh? This is a transmission shifting technique, why would the truck driver shift gears in a low-speed attempt to push the car off the ferry?
giant C-130 (pg. 267) -- Wingspan of a C-130 is around 132 feet. A C-5 is 174 feet, an Airbus is 261 feet, and the Spruce Goose is 320 feet. The C-130 is big, but not GIANT.
a kind of cuddy cabin (pg. 271) -- A small room or a cabin on a small boat, often with limited headspace. Redundant, "cuddy" means "cabin", but that is how the term is often used.
transmit both audio and video signals on a special subsonic frequency to a satellite in space (pg. 285) -- Subsonic is below 20 Hz. Submarines used ELF communication techiniques, but the wavelength is thousands of kilometers, which means a VERY large antenna. I remember reading that the data rate is VERY slow, so I think video/audio transmission would not work. Not to mention satellite communication. Feel free to correct me on this!
Glass shattered in the window, breaking the pane (pg. 363) -- I thought the glass was the pane.
pallentized gunship C-130 (pg. 307) -- Not sure what that means, most C-130s could handle pallets. I slept on a pallet of toolboxes on a C-130 while TDY once.
Jolly Green Giant (pg. 307) -- Sikorsky HH-53 helicopter. Not a C-130, as far as I can find. Maybe the author was thinking of "Puff", a nickname ofr an AC-47 gunship.
palletized hundred-and-five-millimeter howitzer (pg. 308) -- I can't find any mention that the 105mm is on a pallet. Why all the mention of pallets in this novel, it doesn't make it shoot any better!
pediments (pg. 353) -- A triangular element, similar to or derivative of a Grecian pediment, used widely in architecture and decoration.
a Navy diver saved my life (pg. 359) -- Well, he was a SEAL, so he is kind of a SUPER-diver, eh?
Fastened ... with black electrical tape (pg. 421) -- In my experience electrical tape doesn't stick to stuff all that well. We are talking about a nuclear weapon here, why not spring for the good stuff, like duct tape?
