Blackbird SR 71 Nothing But Pratt Engine Sound

To all engine fans’. The original film has been re-edited and a remix of only the sound of the Pratt & Whitney J58-P4 is in this film. Some music from the original snd track is here but barely heard after 15 sec. The clip of ’start up’ is small in screen size, so the picture quality is better. As for the rest of the film, well the size was originally over 10Gig, remember letter box? Well, this is view box. Thanks to Alec Munhapa & Tim Johns you now only hear The Pratt!
