A fantastic 'D' movie (or was it a 'F')?

IMHO, monster movies where everything is so preposterous may provide a peculiar sort of enjoyment, mainly based on unintended humor. I'm glad I recorded this movie when a local tv channel broadcasted it during the night.

In my personal hit parade of such movies this one is on a par with the "best" I've ever watched, i.e. "Sharktopus" and another one, of which I didn't catch the title, based on a humongous snake, radioactive and venomous, that pestered the inhabitants of a hawaiian village and, after receiving literally tons of projectiles from automatic weapons without a hitch, was finally put to sleep with a "maverick" missile (fired point blank within an apartment!).

I won't describe further the movie, since the previous posts have already done a very good job, but I'd like to point out a couple of things about the final aerial assault to the island:

- Trying to annihilate monsters/people on a large island with a dozen napalm missiles is ludicrous enough

- All the scenes with fighters are stock footage. In one of them, two F14's fly to attack with the landing hooks out! The attack seems to start from a carrier, but later a F16 is shown (these fighters are not carrier-based).

- The scenes where the effects of napalm bombardment are shown are either very cheap effects (the impact results in a "fireball" radius not larger than a couple of meters) or footage from other war movies.
A large fire with explosions is displayed, that is taken from another movie about the war in Vietnam. A row of burning huts is clearly visible. I guess the footage is from "Apocalypse Now" or "Bat 21", but I"m not sure about it (and too lazy to inspect those movies, which I own on DVD).
