I didn't remember a black Vietnam flick by Singleton - when I look up his filmography, I don't see one in the past, nor among his future projects. I'm not sure which movie you're referring to...
I saw it on VCR with a group of Serbian refugees....the last part of the film has a few printed lines on the screen, where it was stated that the Admiral who risked his command to make sure the pilot was rescued and the muslims of Bosnia got a victory, was thereafter, given a DESK JOB AT THE PENTAGON....well, at this point, my husband said....
"WHERE HE WAS SITING ON 9/11, when an Arabic muslim terrorist with a BOSNIAN PASSPORT...FLEW AN AIRLINER INTO THE BUILDING....MUCH TO HIS DISMAY...AND SINCEREST REGRETS SINCE HE SUPPORTED THE BOSNIAN MUSLIMS AND ARABIC MUJAHADEEN IN ALL THEIR EFFORTS TO KILL THE NON-MUSLIMS OF BOSNIA".
