I remember the B-52 "Tall Tail" sticking out of the water in the movie, also and I agree it was most likely a mock-up.
Actually the representation of a crashed B-52 in South Vietnam or Cambodia during that time frame (guessing it was supposed to be somewhere between 1968 and 1970 or so) was not very accurate. As far as I know there were no B-52s that were lost in that area. I believe all B-52 losses were over North Vietnam, Thailand, near Guam, over the South China Sea off of South Vietnam and a couple over Laos at the end of 1972.
