This had a prequel or a sequel (can't remember which?) I think it was called the Manhattan Project or something along those lines, where in 1940-45 two pilots are thrust into the future (present day to us, future to them). During an atmospheric experiment which goes awry opening the subspace portal that the U.S.S. Nimitz uses in this film to travel back to 1941. Anyway, they must get back A.S.A.P. as they are suffering the effects of radiation poisoning due to being "out of time" or something like that. I only remember this film vaguely as you can probably tell.
Can anyone find any reference to this film, I can't find it any where
