“The Galloping Ghost is one of nine hundred P-51-15-NA type Mustangs produced by NAA during World War II. It was originally delivered to the Army Air Forces (AAF) on 23 December 1944 and later was assigned to the Third Air Force before being declared surplus on 25 October 1945 and put in storage at Walnut Ridge, Arkansas.”
There was no fireball because of good engineering and limited fuel on board.
I looked for the fuel cell(s) and could not see it in the wreckage. About the only identifiable parts were from the engine.
